SLOW COOKER SMOTHERED PEPPER AND ONION BURGER STEAKS INGREDIENTS

This easy crockpot dinner combines seasoned ground beef patties with sliced vegetables and homemade brown gravy.

You’ll need:

For the Burger Steaks:

2 pounds of ground beef, preferably 85% lean
½ cup of plain breadcrumbs
1 large egg
2 tablespoons of whole milk
1 tablespoon of Worcestershire sauce
1 teaspoon of onion powder
1 teaspoon of garlic powder
1 teaspoon of kosher salt
½ teaspoon of ground black pepper
1 tablespoon of olive oil, for browning

For the Peppers and Onion Gravy:

1 large yellow onion, thinly sliced
1 large green bell pepper, seeded and sliced into strips
1 large red bell pepper, seeded and sliced into strips
3 cloves of garlic, minced
2 cups of low-sodium beef broth
1 tablespoon of Worcestershire sauce
1 tablespoon of tomato paste
1 teaspoon of Dijon mustard
½ teaspoon of dried thyme
½ teaspoon of smoked paprika
2 tablespoons of cornstarch
2 tablespoons of cold water
1 tablespoon of freshly chopped parsley, for optional garnish

WHAT IS THE BEST GROUND BEEF FOR BURGER STEAKS?

Ground beef with an 85/15 lean-to-fat ratio is a great choice for this recipe.

It has enough fat to help keep the patties moist while they cook, without leaving an excessive amount of grease in the gravy.

You can also use 80/20 ground chuck for a richer result. Just be sure to drain off excess grease after browning.

Extra-lean ground beef will work, but the finished hamburger steaks may be slightly firmer and less juicy.

PRO TIP:

Avoid mixing the ground beef too much when preparing the patties. Overworking the meat can give your hamburger steaks a dense, firm texture instead of a tender bite.

INGREDIENT SUBSTITUTIONS AND ADDITIONS

GROUND BEEF: Ground turkey can be substituted for beef, although it produces a lighter-tasting dish. Turkey patties need to reach an internal temperature of 165°F.

BELL PEPPERS: Use any combination of red, yellow, orange, or green bell peppers. Red and yellow peppers have a sweeter flavor, while green peppers provide a slightly more earthy taste.

ONIONS: Yellow onions are excellent for this recipe because they become sweet and tender during cooking. Sweet onions or white onions will also work.

BREADCRUMBS: Plain breadcrumbs help bind the beef mixture. You can substitute seasoned breadcrumbs, but reduce the additional salt and seasonings if needed.

MUSHROOMS: Add 8 ounces of sliced cremini or white button mushrooms for an even heartier gravy. They pair especially well with the onions and beef.

SPICE: For a little heat, add ¼ teaspoon of crushed red pepper flakes or a pinch of cayenne pepper to the gravy.

BEEF BROTH: Low-sodium beef broth gives you more control over the saltiness of the sauce. Regular broth can also be used, but taste the finished gravy before adding any additional salt.

HOW TO MAKE SLOW COOKER SMOTHERED PEPPER AND ONION BURGER STEAKS

These flavorful hamburger steaks are easy to prepare with just a skillet and a slow cooker.

A 6-quart crockpot works well for this recipe.

STEP ONE: PREPARE THE GROUND BEEF MIXTURE

In a large mixing bowl, combine the ground beef, breadcrumbs, egg, milk, Worcestershire sauce, onion powder, garlic powder, salt, and black pepper.

Use clean hands or a large spoon to gently mix everything until combined.

The breadcrumbs and egg help the patties hold together while the milk keeps the mixture moist.

STEP TWO: SHAPE THE BURGER STEAKS

Divide the ground beef mixture into six equal portions.

Shape each portion into an oval patty approximately ¾ inch thick.

Press a shallow indentation into the center of each steak with your thumb. This helps reduce puffing as the meat cooks.

PRO TIP:

Try to keep the hamburger steaks the same thickness so they cook evenly. Making them too thin can cause them to break apart when transferred to the crockpot.

STEP THREE: BROWN THE BEEF PATTIES

Heat the olive oil in a large skillet over medium-high heat.

Add the hamburger steaks in batches and cook for approximately two minutes on each side, until nicely browned.

The patties do not need to be fully cooked at this stage. They will finish cooking in the slow cooker.

Carefully remove them from the skillet and set them aside on a plate.

Browning gives the outside of the meat a deeper flavor and helps the patties hold their shape.

STEP FOUR: COOK THE PEPPERS AND ONIONS

Add the sliced yellow onion, green bell pepper, and red bell pepper to the same skillet.

Cook for three to four minutes, stirring occasionally, until the vegetables begin to soften.

Add the minced garlic and cook for another 30 seconds, just until fragrant.

The vegetables will continue softening in the crockpot, so there’s no need to cook them completely.

STEP FIVE: ADD EVERYTHING TO THE SLOW COOKER

Place half of the cooked peppers and onions into the bottom of the slow cooker.

Arrange the browned burger steaks over the vegetables. Slight overlapping is fine if needed.

Spread the remaining peppers and onions over the top of the patties.

This helps distribute the vegetables throughout the dish while allowing the beef to cook in the flavorful sauce.

STEP SIX: PREPARE THE BROWN GRAVY

In a medium mixing bowl, whisk together the beef broth, Worcestershire sauce, tomato paste, Dijon mustard, dried thyme, and smoked paprika.

Pour approximately ½ cup of the mixture into the warm skillet and scrape up any browned bits from the bottom.

Add this liquid back to the bowl, then pour the entire gravy mixture over the burger steaks and vegetables.

STEP SEVEN: SLOW COOK UNTIL TENDER

Cover the crockpot with its lid.

Cook on LOW for three to four hours or on HIGH for approximately 1½ to 2½ hours, until the centers of the patties reach 160°F.

The exact cooking time will depend on your slow cooker and the thickness of the beef patties.

Keep the lid closed as much as possible so the slow cooker maintains its temperature.

STEP EIGHT: THICKEN THE GRAVY

Carefully transfer the cooked burger steaks to a serving plate and cover loosely with foil.

In a small bowl, whisk together the cornstarch and cold water until smooth.

Stir the cornstarch mixture into the hot gravy and vegetables.

Turn the slow cooker to HIGH, cover, and cook for another 15 to 25 minutes, or until the sauce thickens.

If the gravy isn’t hot enough to thicken, transfer it to a saucepan and simmer for a few minutes.

STEP NINE: SERVE

Return the hamburger steaks to the thickened gravy.

Gently spoon the peppers, onions, and sauce over each patty.

Sprinkle with freshly chopped parsley if desired, and serve hot with your favorite side dishes.

TIPS FOR MAKING THE BEST SLOW COOKER HAMBURGER STEAKS

A few simple techniques will help give you tender beef patties and plenty of delicious gravy.

BROWN THE MEAT FIRST: While you can place uncooked patties directly into the slow cooker, browning improves their flavor and helps them stay together during cooking.

DON’T OVERMIX: Gently combine the ground beef ingredients. Mixing too aggressively can make the finished patties tough.

SLICE THE VEGETABLES EVENLY: Cut the peppers and onions into similar-sized strips so they soften at approximately the same rate.

USE LOW-SODIUM BROTH: Worcestershire sauce already contributes saltiness, so starting with reduced-sodium broth helps keep the flavors balanced.

CHECK THE TEMPERATURE: Use an instant-read thermometer to make sure the center of each burger steak reaches 160°F. Avoid leaving the patties cooking much longer than necessary.

THICKEN AT THE END: Wait until the beef has finished cooking before adding the cornstarch slurry. This gives you more control over the gravy’s consistency.

HOW TO FIX THIN OR THICK GRAVY

The sauce should be thick enough to coat a spoon but still pour easily over the beef.

GRAVY IS TOO THIN: Combine one additional tablespoon of cornstarch with one tablespoon of cold water. Stir it into the hot gravy and allow it to cook until thickened.

GRAVY IS TOO THICK: Add beef broth, two tablespoons at a time, until the gravy reaches your preferred consistency.

GRAVY IS TOO SALTY: Stir in a small amount of unsalted beef broth or water. Avoid adding more Worcestershire sauce or salt until you’ve tasted it again.

GRAVY HAS LUMPS: Make sure the cornstarch dissolves completely in cold water before adding it to the sauce. Never sprinkle dry cornstarch directly into hot gravy.

HOW TO SERVE SMOTHERED BURGER STEAKS

These juicy hamburger steaks are delicious with simple side dishes that can soak up the rich brown gravy.

MASHED POTATOES: Creamy mashed potatoes are one of the best choices. Spoon a burger steak over the potatoes and add plenty of peppers, onions, and gravy.

WHITE RICE: Fluffy white rice is another excellent option. The mild flavor pairs beautifully with the savory beef sauce.

EGG NOODLES: Serve the hamburger steaks over buttery egg noodles for a hearty dinner that’s especially good on chilly evenings.

ROASTED VEGETABLES: Green beans, roasted carrots, or steamed broccoli add color and freshness alongside the rich beef.

DINNER ROLLS: Warm dinner rolls or crusty bread are perfect for soaking up any extra gravy left on the plate.

For a complete family meal, serve the beef with mashed potatoes, green beans, and a simple green salad.

HOW TO STORE SLOW COOKER BURGER STEAKS

This is an excellent recipe for preparing ahead of time or saving leftovers for another meal.

MAKE AHEAD

You can prepare the uncooked beef patties up to 24 hours in advance.

Place them in a single layer in an airtight container, separating layers with parchment paper if necessary.

Keep the sliced peppers and onions in a separate covered container in the refrigerator.

The gravy ingredients can also be mixed ahead of time, except for the cornstarch slurry.

When you’re ready to cook, brown the patties and follow the remaining recipe instructions.

IN THE FRIDGE

Transfer the cooked hamburger steaks, vegetables, and gravy to airtight containers.

Refrigerate within two hours of cooking.

Properly stored leftovers will keep in the refrigerator for three to four days.

Keeping the patties covered with gravy helps prevent them from drying out.

IN THE FREEZER

Allow the leftovers to cool before placing them in freezer-safe containers.

Add enough gravy to cover the burger steaks and leave a little room for expansion.

Freeze for up to three months for the best quality.

Thaw overnight in the refrigerator before reheating.

REHEATING

STOVETOP: Place the hamburger steaks and gravy in a covered skillet over medium-low heat. Add a splash of beef broth if necessary and warm until the center of the meat reaches 165°F.

MICROWAVE: Transfer one serving to a microwave-safe dish, cover loosely, and heat in short intervals until thoroughly heated.

OVEN: Place the steaks and gravy in a covered baking dish and reheat at 325°F until hot throughout and the patties reach 165°F.

FREQUENTLY ASKED QUESTIONS

Can I put raw hamburger steaks directly into the slow cooker?

Yes. You can skip browning the patties, although they will have a softer texture and less browned flavor. Make sure the beef reaches an internal temperature of 160°F before serving.

Why are my hamburger steaks falling apart?

This usually happens when the meat mixture hasn’t been combined evenly or the patties are handled too much during cooking.

Using the egg and breadcrumbs helps hold everything together. Browning the patties before slow cooking also makes them easier to handle.

Can I make this recipe without bell peppers?

Absolutely. Leave out the bell peppers and add another sliced onion or 8 ounces of sliced mushrooms.

The finished dish will still have plenty of rich beef flavor.

Can I use frozen hamburger patties?

Thaw the patties completely in the refrigerator before cooking. Frozen ground beef patties should not be placed directly into the slow cooker because they may heat too slowly.

How do I keep the burger steaks from drying out?

Choose ground beef with some fat, avoid overmixing, and check the internal temperature toward the beginning of the recommended cooking window.

Cooking the patties in gravy also helps keep the finished dish moist.

These slow cooker smothered pepper and onion burger steaks make a comforting dinner with tender beef, soft vegetables, and plenty of homemade gravy. Serve them over mashed potatoes or rice for a filling meal that’s easy enough to make any night of the week.
