How to Make Garlicky Avocado Grilled Cheese with Tomato Pesto Recipe

Step 1: Prepare the Garlic-Herb Butter

Start by mixing the salted butter with onion powder, garlic powder, kosher salt, and dried thyme. Mash it all together in a small bowl until perfectly combined. This butter is the secret ingredient that delivers that crave-worthy crust and incredible garlicky aroma.

Step 2: Butter the Bread

Spread the onion garlic butter mixture on one side of each slice of bread. Then flip the slices so the buttered side is facing down; this side will get crispy and golden in the pan.

Step 3: Layer the Sandwich

On the bottom slice of bread (butter side down), start layering a few slices of provolone cheese. Spread the mashed avocado evenly on top, then dollop the sun-dried tomato pesto over the avocado for a punch of tangy flavor. Cover with the remaining provolone cheese slices and finally place the other bread slice on top, buttered side up.

Step 4: Cook the Sandwich

Heat a large non-stick pan over low heat and add the olive oil along with a little extra of the garlic butter mix. Place the sandwich in the pan, cover with a lid, and cook gently for 3 to 4 minutes. This slow cooking lets the bread toast to a golden crisp without burning, while the cheese starts to melt inside perfectly.

Step 5: Flip and Finish Cooking

Carefully flip the sandwich to the other side and cook for another 2 to 3 minutes until this side is golden and the cheese is fully melted. Keep an eye on it since it cooks faster once flipped. Once done, take it off the heat and get ready to savor every gooey, flavorful bite.

Each sandwich is made of two golden-brown toasted bread slices with a slightly rough texture and some herbs visible on top. The sandwiches are filled with layers of melted light yellow cheese and green avocado spread, which is creamy and slightly chunky. The melted cheese oozes slightly from the edges, blending with the avocado inside. One sandwich has a bite taken out of it, revealing the soft, gooey cheese and small pieces of avocado.

Garnishes

A sprinkle of freshly cracked black pepper or a few red pepper flakes on top elevates the flavors with a hint of heat. You can also add a few torn fresh basil leaves to brighten up the sandwich and add a pop of green color.

Side Dishes

This Garlicky Avocado Grilled Cheese with Tomato Pesto Recipe pairs beautifully with a crisp garden salad, some roasted tomato soup, or even a handful of crunchy pickles to complement its rich, creamy profile perfectly.

Creative Ways to Present

For a fun twist, cut your sandwich into triangles or strips and serve alongside a small bowl of extra tomato pesto for dipping. You can also make mini versions on slider buns for a crowd-pleasing appetizer or snack.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, wrap the sandwich tightly in plastic wrap or foil and store it in the refrigerator for up to 2 days. The bread may not stay as crispy, but the flavors remain delicious throughout.

Freezing

While it’s best enjoyed fresh, you can freeze this sandwich before cooking. Wrap it tightly and freeze for up to one month. When ready, thaw overnight in the fridge and cook as directed, adding a few extra minutes if necessary to ensure the cheese melts fully.

Reheating

To reheat, place the sandwich in a skillet over low heat, covering it to help the cheese soften again. Avoid the microwave if possible, as reheating that way can result in soggy bread and uneven melted cheese.

FAQs

Can I use different types of cheese instead of provolone?

Absolutely! Mozzarella, fontina, or even sharp cheddar would work wonderfully. Just choose cheeses that melt well to get that lovely gooey texture.

Is sun-dried tomato pesto hard to find?

Not at all! Most grocery stores carry it in the condiment or Italian foods section. You can also make a quick homemade version by blending sun-dried tomatoes with olive oil, garlic, and herbs.

Can I make this sandwich vegan or dairy-free?

You can! Use a plant-based butter alternative, vegan cheese slices that melt, and make sure your bread doesn’t contain dairy. The avocado and pesto will still provide amazing flavor.

What bread do you recommend for the sandwich?

Whole wheat white bread adds nice texture and flavor, but any sturdy bread like sourdough or multigrain will hold the fillings well and toast up beautifully.

Can I skip the olive oil in cooking?

Yes, but the olive oil helps the garlic butter spread evenly and prevents sticking. If you prefer, you can cook just in the garlic butter mixture for great results.
