This creamy avocado grilled cheese saved me from another boring lunch when I was staring at perfectly ripe avocados and wondering what to do with them besides the usual toast situation. The mashed avocado mixed with melty mozzarella and sharp cheddar creates this incredibly rich, satisfying sandwich that's way more interesting than regular grilled cheese but still hits all those comfort food notes. I first tried this combination on a whim when my kids were getting tired of plain grilled cheese, and now they actually get excited about lunch again.

My neighbor's teenage daughter, who claims she "doesn't really like avocado," tried one of these and immediately asked me to teach her how to make them. Now she makes them after school and her friends always want to know what smells so good when they come over.

What Goes Into It

  • Really ripe avocado: Should give slightly when you press it but not be mushy
  • Good melting cheeses: Mozzarella and cheddar are the perfect combo here
  • Decent bread: Whatever you'd use for regular grilled cheese works great
  • Mayo for the spread: Sounds weird but makes the outside incredibly golden
  • Simple seasonings: Just garlic and onion powder to boost the flavors

Getting It Done

Prepping everything
Get your skillet going over medium heat while you mash up the avocado with some salt and pepper. Don't make it completely smooth - a little texture is good. Mix your cheeses together in a bowl so you can grab them quickly.
Setting up the bread
Spread butter on one side of each slice, then put mayo on the unbuttered side of two pieces. I know mayo sounds strange, but trust me on this - it makes the outside incredibly crispy and golden.
Building them up
Put the mayo slices face-down in your pan, then spread that mashed avocado over each piece. Sprinkle on the garlic and onion powder, pile on the cheese mix, add some basil if you've got it, then top with the other bread pieces butter-side up.
Making them perfect
Cook about 3-4 minutes per side until they're golden and the cheese is completely melted. Don't crank the heat too high or you'll burn the outside before the cheese melts.

I learned that timing the avocado ripeness is everything. I used to buy them and forget about them until they were either rocks or mush. Now I plan a day or two ahead and they're perfect when I want to make these.

How to Serve Them

These are rich enough to be lunch by themselves, but they're great with some chips or a simple salad. The creaminess really pairs well with something crunchy and acidic like pickles. My kids love them with apple slices on the side.

Making Them Different

Sometimes I throw in some crispy bacon or sliced tomatoes for extra flavor. Different herbs work too - cilantro or oregano instead of basil can completely change the vibe. You could probably use different cheeses based on what you have around.

Frequently Asked Questions

→ What type of bread works best for avocado grilled cheese?
Day-old sourdough or thick white bread works great because it holds up well to the avocado without getting soggy.
→ How do I keep the avocado from making the bread soggy?
Use ripe but firm avocado and don't mash it too much. Also, cook the sandwich right after assembling it.
→ Can I make this sandwich ahead of time?
It's best made fresh, but you can prep the avocado mixture and grate cheese ahead. Assemble and cook when ready to eat.
→ What other cheeses work well with avocado?
Try pepper jack for spice, swiss for mild flavor, or gouda for something rich. The key is using good melting cheeses.
→ How do I know when the sandwich is done?
The bread should be golden brown and crispy, and you should see the cheese melting and slightly oozing out the sides.

Yield: 2 Servings

Ingredients

→ Main Components

01 4 thick slices of your favorite bread
02 1 perfectly ripe avocado
03 1 cup freshly shredded mozzarella cheese
04 1 cup freshly shredded sharp cheddar cheese

→ Flavor Enhancers

05 2 tablespoons butter, softened to room temperature
06 1 tablespoon creamy mayonnaise
07 ½ teaspoon garlic powder
08 ½ teaspoon onion powder
09 Sea salt and freshly ground black pepper
10 ¼ cup fresh basil leaves (if you have them on hand)

Instructions

Step 01

Heat a large skillet or griddle over medium heat. You want it nice and warm but not smoking hot.

Step 02

Scoop out your avocado and mash it up with a fork until it's creamy but still has some texture. Season with a pinch of salt and pepper.

Step 03

Toss both cheeses together in a bowl so they're evenly mixed. This helps them melt together perfectly.

Step 04

Spread softened butter on one side of each bread slice. On the unbuttered side of two slices, spread a thin layer of mayo.

Step 05

Place the mayo-spread slices in your heated pan, mayo-side down. Spread the seasoned avocado evenly over each slice, then sprinkle with garlic and onion powder.

Step 06

Pile on your cheese mixture generously over the avocado. If you're using basil, layer those fresh leaves on top of the cheese.

Step 07

Top with the remaining bread slices, butter-side facing up. Cook for 3-4 minutes until the bottom is golden brown and crispy.

Step 08

Carefully flip your sandwiches and cook another 3-4 minutes until both sides are golden and the cheese is completely melted and gooey.

Step 09

Remove from heat, let cool for just a minute, then slice diagonally and serve while the cheese is still stretchy and warm.

Notes

  1. This sandwich works best with day-old bread that won't get soggy from the avocado
  2. Make sure your avocado is ripe but not overripe for the best texture
  3. Keep the heat at medium to avoid burning the outside before the cheese melts
