WHAT IS SOUR CREAM SWISS STEAK?
Swiss steak is a traditional beef dish made with round steak that’s tenderized and cooked slowly in a flavorful sauce.
Despite its name, Swiss steak doesn’t contain Swiss cheese. The name comes from a method of tenderizing meat, sometimes called swissing, which helps soften tougher cuts of beef.
Traditional versions often feature tomatoes, onions, and beef broth. This creamy variation uses condensed mushroom soup, onion seasoning, and sour cream instead.
The result is tender slices of beef covered in a thick, savory gravy with a slightly tangy finish.
Unlike recipes that require several steps on the stovetop, this version cooks almost entirely in the oven. The covered baking dish holds in moisture, allowing the beef to become tender without needing constant attention.
OVEN BAKED SOUR CREAM SWISS STEAK INGREDIENTS
One of the best things about this recipe is its short ingredient list. Each ingredient contributes to the flavor and texture of the finished dish.
You’ll need:
- 2 pounds of boneless beef round steak, cut into six serving-size pieces, approximately ¾ to 1 inch thick
- 2 (10.5-ounce) cans of condensed cream of mushroom soup
- 1 (1-ounce) packet of dry onion soup mix
- 1 cup of full-fat sour cream
INGREDIENT NOTES
ROUND STEAK: Beef round steak is ideal for this recipe because it becomes more tender when cooked slowly with moisture. Top round or bottom round steak will both work.
Look for pieces with an even thickness so they cook at approximately the same rate.
CREAM OF MUSHROOM SOUP: Condensed cream of mushroom soup creates the base of the gravy. It gives the sauce a thick consistency and adds a savory mushroom flavor that complements the beef.
Use condensed soup directly from the cans. There’s no need to dilute it with water before baking.
ONION SOUP MIX: A packet of dry onion soup mix adds onion flavor and seasoning without chopping or cooking fresh onions.
The seasoning mix also contains salt, so you shouldn’t need to add additional salt before tasting the finished dish.
SOUR CREAM: Full-fat sour cream gives the gravy its creamy texture and slightly tangy flavor. It is stirred into the hot sauce at the end of cooking to help prevent curdling.
WHAT IS THE BEST BEEF FOR SWISS STEAK?
Round steak is one of the best choices for oven baked Swiss steak.
It’s a relatively lean cut with muscle fibers that can make it chewy when cooked quickly. Slow cooking in a covered baking dish gives those fibers time to soften.
Top round tends to be a little more tender than bottom round, although either cut works well.
You can also use cube steak for this recipe. Because cube steak has already been mechanically tenderized, it may become tender sooner.
Avoid substituting very thin sandwich steaks without adjusting the cooking time. They can fall apart or dry out during a long bake.
HOW TO MAKE OVEN BAKED 4-INGREDIENTS SOUR CREAM SWISS STEAK
This easy Swiss steak recipe takes about 15 minutes to prepare. The oven handles the rest of the cooking.
For the best results, use a deep 9×13-inch baking dish with a tightly fitting cover or aluminum foil.
STEP ONE: PREHEAT THE OVEN
Preheat your oven to 325°F.
Lightly arrange your baking dish and ingredients on the counter so everything is ready to assemble.
A covered dish is important because the beef needs moisture to become tender during baking.
STEP TWO: PREPARE THE BEEF
Place the round steak on a cutting board and cut it into six serving-size pieces.
If the pieces are unusually thick, gently pound them with a meat mallet until they’re approximately ¾ to 1 inch thick.
Pat the beef dry with paper towels.
You don’t need to brown the steak before baking. This recipe relies on slow, covered cooking to make the meat tender.
PRO TIP:
Cutting the beef into similar-size pieces helps ensure that every serving cooks evenly. Smaller, thinner pieces may become tender before thicker ones.
STEP THREE: ARRANGE THE STEAK
Place the beef pieces in a single layer in the bottom of your baking dish.
A little overlapping is fine, but avoid stacking all the meat in one thick pile.
Leaving some space between pieces allows the sauce to surround the beef as it cooks.
STEP FOUR: PREPARE THE MUSHROOM GRAVY
In a medium mixing bowl, combine the two cans of condensed cream of mushroom soup with the packet of dry onion soup mix.
Stir until the onion seasoning is distributed throughout the soup.
The mixture will be thick at this stage. That’s normal.
As the beef cooks, it releases juices that help loosen the condensed soup and create a rich gravy.
STEP FIVE: ADD THE SAUCE
Spoon the mushroom soup mixture evenly over the round steak.
Use the back of a spoon to spread the sauce across the top, making sure every piece is covered.
Try to work some of the gravy between the pieces of meat.
This helps keep the beef moist while it bakes.
STEP SIX: COVER THE BAKING DISH
Cover the baking dish tightly with aluminum foil or an oven-safe lid.
Make sure the edges are sealed well.
Trapping the steam inside the dish is one of the most important parts of this recipe. If too much moisture escapes, the sauce can become overly thick before the beef is tender.
STEP SEVEN: BAKE UNTIL TENDER
Place the covered baking dish in the preheated oven.
Bake for approximately 2½ hours, checking the beef for tenderness after two hours.
Depending on the thickness and cut of steak, it may need up to three hours.
The meat is ready when a fork slides into it easily and the beef can be pulled apart without much resistance.
PRO TIP:
If the steak still feels firm after two hours, cover the dish again and continue baking in 20-minute intervals.
Round steak often needs additional cooking time to become tender. Removing it too early can leave the meat chewy.
STEP EIGHT: ADD THE SOUR CREAM
Remove the baking dish from the oven and carefully lift the foil away from you to release the hot steam.
Let the sauce settle for about five minutes.
Place the sour cream in a bowl and gradually stir in several spoonfuls of the warm mushroom gravy.
This helps bring the sour cream closer to the temperature of the sauce.
Gently stir the mixture back into the baking dish until the gravy becomes smooth and creamy.
Avoid boiling the sauce after adding the sour cream, as high heat can cause it to separate.
STEP NINE: SERVE
Spoon the creamy mushroom gravy over the tender steak.
Serve immediately with your favorite side dishes, making sure each portion gets plenty of sauce.
TIPS FOR MAKING THE BEST OVEN BAKED SWISS STEAK
A few simple tips can make a big difference when cooking this creamy beef recipe.
KEEP THE DISH COVERED: The beef needs a moist cooking environment. Covering the dish tightly prevents excessive evaporation and helps keep the gravy from drying out.
DON’T RUSH THE COOKING TIME: Round steak becomes tender with slow cooking. If the meat is still difficult to cut, it likely needs more time in the oven.
USE FULL-FAT SOUR CREAM: Full-fat sour cream generally produces a smoother, richer sauce and is less likely to separate than reduced-fat varieties.
CHECK THE GRAVY: The finished sauce should be thick enough to coat a spoon but still easy to pour over the beef.
LET THE MEAT REST: Allowing the dish to stand briefly before serving makes the sauce easier to mix and gives the beef time to settle.
SOUR CREAM SWISS STEAK SUBSTITUTIONS AND ADDITIONS
The original recipe only requires four ingredients, but there are a few ways to change the flavor if you want something different.
BEEF: Cube steak is an easy substitute for round steak. Chuck steak can also work, although its higher fat content produces a richer finished dish.
SOUP: Cream of celery soup can replace cream of mushroom soup for a slightly different flavor. Cream of chicken soup is another option, although the sauce will have less mushroom flavor.
SOUR CREAM: Reduced-fat sour cream can be substituted, but it may produce a thinner sauce and can separate more easily when heated.
ONION SEASONING: Different brands of onion soup mix may vary in saltiness. Choose a lower-sodium variety if you prefer greater control over the seasoning.
MUSHROOMS: For extra mushroom flavor, add 8 ounces of sliced fresh mushrooms before baking.
ONIONS: Half a cup of thinly sliced yellow onions adds texture and a little sweetness to the gravy.
WORCESTERSHIRE SAUCE: One teaspoon can give the sauce a deeper, savory flavor.
Remember that these optional additions change the original four-ingredient recipe.
HOW TO SERVE SOUR CREAM SWISS STEAK
This oven baked Swiss steak is delicious served with something that can soak up the creamy mushroom gravy.
MASHED POTATOES: Creamy mashed potatoes are one of the best choices. Spoon a piece of tender steak over the potatoes and finish with a generous helping of gravy.
EGG NOODLES: Wide egg noodles are another excellent option. Their soft texture pairs beautifully with the rich sauce.
RICE: Fluffy white rice makes a simple side dish and helps stretch the recipe when you’re feeding a family.
ROASTED VEGETABLES: Roasted carrots, green beans, or broccoli add color and balance the richness of the meal.
DINNER ROLLS: Warm dinner rolls or crusty bread are perfect for soaking up any extra gravy left on the plate.
For an easy weeknight dinner, serve the steak with mashed potatoes and steamed green beans. It’s a filling meal without requiring much additional preparation.
HOW TO STORE SOUR CREAM SWISS STEAK
This recipe is convenient for leftovers, especially when the beef and gravy are stored together.
MAKE AHEAD
You can assemble the steak, condensed soup, and onion seasoning in the baking dish up to 24 hours before cooking.
Cover tightly and refrigerate.
When you’re ready to bake, place the dish in the oven once the oven-safe dish has warmed slightly from refrigerator temperature, following the manufacturer’s guidance.
Add the sour cream after the beef has finished cooking, just as directed in the recipe.
IN THE FRIDGE
Allow the cooked Swiss steak to cool slightly, then transfer it to an airtight container.
Refrigerate within two hours of cooking and store for up to three to four days.
Keep the meat covered with gravy to help prevent it from drying out.
IN THE FREEZER
For the best texture, freeze the cooked beef and mushroom gravy before adding the sour cream.
Place the cooled beef and sauce in a freezer-safe container and freeze for up to three months.
Thaw overnight in the refrigerator, reheat thoroughly, and stir in the sour cream before serving.
Leftovers that already contain sour cream can also be frozen, although the sauce may become slightly grainy after thawing.
REHEATING
Place leftovers in a covered baking dish and warm in a 300°F oven until heated through to 165°F.
You can also reheat individual servings in the microwave using short intervals.
Stir the gravy gently between intervals and avoid boiling it unnecessarily.
TROUBLESHOOTING THIS SWISS STEAK RECIPE
WHY IS MY SWISS STEAK TOUGH?
Round steak contains connective tissue that takes time to soften. If the meat is still chewy, cover the baking dish and continue cooking until it becomes fork-tender.
WHY IS MY GRAVY TOO THICK?
Condensed soup naturally creates a thick gravy. If it becomes thicker than you prefer, stir in a small amount of warm water, one tablespoon at a time, until it reaches the desired consistency.
WHY DID MY SOUR CREAM SAUCE SEPARATE?
Sour cream can curdle when exposed to excessive heat. Tempering it with warm gravy before stirring it into the dish helps reduce this problem.
WHAT IF THE SAUCE IS TOO SALTY?
Onion soup mix and condensed mushroom soup both contain sodium. Choose reduced-sodium versions when possible and avoid adding extra salt until you’ve tasted the finished gravy.
FREQUENTLY ASKED QUESTIONS
Can I make sour cream Swiss steak without browning the meat?
Yes. Browning adds additional flavor, but it isn’t necessary for this recipe. The beef cooks slowly in the mushroom gravy, making this an easy dinner with very little preparation.
Do I need to tenderize the round steak first?
You can gently pound thicker pieces with a meat mallet, but it’s optional. Cooking the beef slowly in a covered dish is what helps make it tender.
Can I use frozen steak?
Thaw the steak completely in the refrigerator before assembling the recipe. Frozen beef won’t cook at the same rate, which can affect the tenderness and cooking time.
Can I cook this recipe at 350°F?
Yes, although the higher temperature can cause the gravy to reduce more quickly. Keep the dish tightly covered and check the beef earlier for tenderness. The lower 325°F temperature is preferable for slow, gentle cooking.
Can I make this Swiss steak in a slow cooker?
Yes. Arrange the thawed beef in the slow cooker, add the soup and onion seasoning, and cook on low for approximately six to eight hours, or until fork-tender.
Stir in the tempered sour cream just before serving.
Why should sour cream be added at the end?
Adding sour cream after baking helps keep the gravy creamy and smooth. Cooking sour cream for several hours can cause its proteins to separate, leaving a grainy sauce.
Can I double the recipe?
Yes. Double all four ingredients and use two baking dishes or a large covered roasting pan.
Avoid stacking the beef too deeply, and allow extra cooking time if necessary.
