Creamy Avocado Grilled Cheese

This decadent yet easy avocado grilled cheese sandwich takes the classic grilled cheese up a notch! Melted mozzarella cheese, creamy mashed avocado, and fresh tomato come together for an incredible flavor combination you’ll crave again and again.

A warm, gooey grilled cheese sandwich gets a creamy twist with the addition of fresh avocado. Melted mozzarella cheese, sliced tomato, and buttery toasted brioche bread complement the cool, smooth avocado in each bite. This sandwich makes an easy yet filling lunch or light dinner.

Grilled cheese and avocado are a match made in heaven. The cool creaminess of the mashed avocado balances beautifully with the melted mozzarella cheese. Meanwhile, the toasted brioche bread provides a crunchy exterior and soft interior. The fresh tomato adds a nice burst of acidity and texture.

While a basic grilled cheese is certainly classic, this avocado version is next level. Once you try it, you may never go back to plain grilled cheese again! The avocado adds so much richness and flavor that takes this sandwich over the top.

What type of bread works best for this recipe?

Brioche or a soft white bread like sourdough works very well. The bread should be soft enough to easily spread the butter without tearing it. Avoid using a tougher artisan bread that won’t toast up nicely.

Can I add anything else to this grilled cheese?

Yes, you can customize this grilled cheese by adding crispy bacon, different cheese varieties like cheddar or gruyère, sliced ham, caramelized onions, sautéed mushrooms, etc. Get creative with extra mix-ins!

How do I stop the cheese from oozing out of the bread?

Use enough cheese to melt and ooze deliciously, but don’t overstuff the sandwich. Also, let the cheese melt sufficiently before removing the top slice of bread. If needed, gently press down on the top slice to keep the cheese contained.

How do I keep the bread from burning?

Use medium heat and keep a close eye on it as it cooks. Lower the heat if the bread seems to be browning too quickly. Also, use slightly softened butter that spreads easily without tearing the bread. Evenly buttering the bread helps prevent burning.
