There’s nothing quite like a well-made grilled cheese sandwich, or better yet, an avocado grilled cheese sandwich!
Grilled cheese will always remind me of being a kid. Most days for lunch, I’d eat a turkey and cheese sandwich, but when I wanted a warm sandwich for lunch, I’d whip up a grilled cheese. I think I liked it so much because it was something I could prepare myself vs. needing help from my mom. Honestly, this avocado grilled cheese is the same sandwich I’ve been making for years, but with the addition of avocado because avocado makes everything better!
WHY YOU’LL LOVE THIS AVOCADO GRILLED CHEESE
- It’s an easy, 3-ingredient recipe
- The avocado elevates this sandwich both in flavor and nutrition
- It’s a slightly fancier version of your favorite childhood food

HOW TO MAKE AN AVOCADO GRILLED CHEESE SANDWICH
Soften the butter: If you have a tub of spreadable butter, then you can skip this step. If you’re like me and only have sticks of butter, you’ll have to soften the butter so that you can spread it on the bread. I like to place the tablespoon of butter in the microwave for 10-12 seconds to soften it.
Mash the avocado: While you can use avocado slices on the sandwich, the avocado mash makes it so that when you flip the sandwich in the skillet, the avocado stays in place.
Add the cheese: I’m not a huge fan of packaged sliced cheese, but in the case of a grilled cheese, it is PERFECT. It’s affordable and it melts quickly, which is key when making a grilled cheese.

WHAT KIND OF BREAD SHOULD I USE?
The better the bread, the more delicious this sandwich will taste. I’m a sucker for a good loaf of sourdough bread, which is what I used in this recipe, but feel free to use YOUR favorite kind of bread.
CAN I ADD MORE INGREDIENTS?
Absolutely! This recipe is pretty basic (in a good way!), but if you want to jazz up your sandwich a bit, you could always add bacon, sliced tomato and/or spinach to it.
CAN I USE STORE BOUGHT BUFFALO SAUCE INSTEAD?
Sure can! The whole point of the homemade buffalo sauce is to show you that making your own sauce is incredibly easy. In fact, you might probably definitely already have all of the ingredients?!

I’ve never been a huge buffalo-sauce lover but that sandwich…..ahhhhhhh yum. anything that involves both cheese and avocado is amazing
Yes yes I have to agree!
STOP IT! I wish my taste buds were sophisticated back when I could eat grilled cheese, because I’d be all over this recipe. But of course when I could eat said sandwiches, I didn’t even know what an avocado was!!! Say what?!?!
Oh nooooo! Sad. And ya I only recently discovered the greatness of avocados, and now I’m OBSESSED.
I don’t know what it is, but anything that says “Buffalo Sauce” and it has all my attention! It always sounds super good. But I have to say, I am a mayo lover like Miguel, and I would probably mix the Buffalo Sauce with some Mayo haha
Oh wow haha let me know how that turns out!
Okay I want this NOW, for breakfast.
Also, these pictures are beautiful!
Thanks Amy!
WHAT! This looks amazing! I am totally making these for dinner tomorrow night- thanks girl!
Let me know if you do!
Yayyyyy! I’m so glad you posted this. I have GOT to make it. I have the cheese, avo, and bread so I just gotta make da sauce. Time to get saucy.
MAKE IT lol love your corniness 😉
I’m not a buffalo fan but John looooooves it. Also I’m jealous of your grocery proximity. In Florida, we lived literally across the street from the grocery store and it was glorious. After being so spoiled, no home will ever again feel “close” to the grocery store.
Right? I feel so spoiled now and I know once we move I’ll probably have to drive to the store….*tear*
Oh.my.GOD, girl… I can’t even handle this right now. I’m about to sit down to enjoy breakfast, which is easily my favourite meal of the day, and now you’ve got me craving grilled cheese. Gah!
Hhaha thanks Amanda!
Holy cow this looks amazing!! A sandwich with a dipping sauce I am on board with. I am a wuss when it comes to spice and hot things so I’d make mine without the hot sauce but with everything else 🙂
In summary, YUM!!!
Hhaa oh giiiirl I am a wuss too but no worries this sauce isn’t too spicy.
Um……I was actually telling a co-worker of mine who had been to America and we were hating on Australia for not having buffalo sauce. Legit linking her to this post. Avocado and cheese is perfect…even more so? Add vegemite.
You don’t have buffalo sauce?!! Wtf. Make this stuff–it’s legit the same thing 🙂
