There’s something so satisfying about a well-made sandwich, especially when it’s loaded with flavor and made with wholesome ingredients. This grilled chicken and avocado sandwich is a go-to for lunch or dinner, it’s easy, filling, and packed with the kind of fresh, feel-good ingredients that make every bite worth it.
Start with the star of the show: the grilled chicken breast. A quick marinade of olive oil, lemon juice, garlic, and herbs will take your chicken from basic to bursting with flavor. Grill it until it’s beautifully seared on the outside and juicy on the inside. While the chicken rests, you can prep the other layers.
Creamy avocado plays the perfect counterpart to the savory chicken. Slice or mash it with a little lemon juice, salt, and pepper to enhance its buttery richness. Next, choose your bread. A crusty ciabatta roll, hearty whole grain, or sourdough slice works wonderfully. Toast it lightly for a golden crunch that holds up well to the fillings.
Now it’s time to build. Start with a swipe of mayo, pesto, or even a light garlic aioli if you’re feeling fancy. Layer on your grilled chicken, avocado, and crisp toppings like lettuce, tomato, and red onion. Add a slice of cheese, like Swiss, provolone, or mozzarella, for extra indulgence, or keep it dairy-free for a lighter take.
This sandwich is not only delicious but also well-balanced. You’ve got lean protein, healthy fats, fiber, and just the right amount of carbs to keep you energized without feeling heavy. It’s also endlessly customizable. Swap the chicken for turkey or tofu, or add a spicy element with sliced jalapeños or a chipotle spread.
Serve it with sweet potato fries, a side salad, or just a handful of chips for a satisfying plate. Whether you’re enjoying it hot off the grill or packing it for lunch, this grilled chicken and avocado sandwich delivers all the flavor you crave in a no-fuss meal.
Avocados are often referred to as a “superfood” due to their numerous health benefits. In addition to being heart-healthy, avocados contain antioxidants that can help reduce inflammation, promote eye health, and support healthy aging.
Chicken and avocado sandwiches have gained popularity in recent years due to their healthfulness, flavor, and Instagram-worthy appearance. They are frequently featured on restaurant menus and food blogs, often with creative variations and presentations.

This sandwich is delicious! The avocado makes it so creamy. Will definitely make again!
I gotta try this! Avocado really adds a nice touch, doesn’t it? Thanks for sharing!
I found the chicken a bit dry. Maybe cook it less? Not sure if I’ll try again.
Idk about this recipe, if its grilled chicken I prefer it with BBQ sauce. This is just plain.
Yum! Love how easy this is! I added some spicy mayo and it took it to another level. Will make again!
My kids loved it! Even ate all their veggies, which never happens! Thank you!
This sandwich is amazing! The chicken is so juicy and the avocado makes it so creamy. Definitely a hit in my house!
Yummy!!! 🤤 My kids even liked it!!
It was alright, but I feel like something was missing. Maybe a little spice? Just not that flavorful for me.
Yummy! But why use whole wheat? White bread is tastier!
Just made this for my family and they loved it! So fresh and filling! 🍽️
Grilled chicken with avocado? Who knew it was that easy? Thanks for sharing!
This sandwich was so good! I’ve made it twice already and my family loves it! 😍
I don’t know about this recipe. Is grilled chicken really that good in a sandwich?
This sandwich is a game changer! So simple but sooo delicious! 🤤
I love how easy this recipe is! I can’t wait to try it this weekend. 🤩
YUMMM!!! Avocado on anything is a win! 🥑❤️
Grilled chicken? Isn’t it like the same as fried chicken? What’s the point? 😕
Grilled chicken is way healthier than fried! It’s less greasy and has more flavor. You should give this recipe a try! 😋
Too much bread for me, I like my sandwiches smaller. I guess that’s just how I roll. But the chicken was good.
This is how I like my sandwiches. Simple and fresh! I’ll keep this recipe!
Chicken breast? Why not use thigh? Thigh is tastier and it wouldn’t dry out so much!
Tastes great! I was skeptical about the combo but it’s a winner! So glad I tried this.
I made this but used regular bread and it felt off. Whole wheat is better for sure!
I’m not a big fan of mayo, can I use mustard instead? 🤔
I have no grill… can I use a pan?
Absolutely! Just make sure your pan is really hot. You’ll get a nice sear on the chicken that way.
I guess so, but won’t it be different? Grilled chicken has a smoky flavor or something.
This is too healthy for me. Give me butter and bread any day! 😂
I don’t understand why everyone loves this. The chicken was dry and the mayo made it too soggy. Not great.
Ok but why is everyone so hype about avocado? It’s just green mush. I don’t get it. 🤷♂️
My kids didn’t like it. They said it was ‘too green’ with the avocado. Idk if I’ll try this again. 🤷♀️
Too many ingredients! I just wanted a simple sandwich. Mad at myself for trying this 😒
I get it! Sometimes less is more. A simple grilled cheese could’ve done the trick. 😅
SO GOOD! Plus, avocado and grilled chicken is like, a great combination for health!
I totally agree! Avocado and grilled chicken are the best! I can eat this every day!
It sounds good, but isn’t mayo a bit unhealthy? Maybe try it without?
I tried this recipe and messed up the grilling part. My chicken was dry. Any suggestions on how to fix that?
I dunno, the mayo was too much for me. Maybe I would skip that part next time…
I tried it but my chicken was dry. Maybe I overcooked? Anyone else have that problem?
Wasn’t sure about the avocado but it actually made it taste good! My kids gobbled it up. 😋
2 chicken breasts? I only got one. Will it spoil if I make less? Always confused with servings.
Best thing ever! The combination of avocados and chicken is just perfection. Will repeat for sure!
Can I use regular bread? Whole wheat is hard to come by in my area. Also, what’s garlic powder??
Eh, I prefer peanut butter and jelly sandwiches. At least I know what I’m gettin’ there. 😅
10/10! I’m not a cook or anything, but this was super simple and delicious. I feel like a chef lol.
I’m so glad you liked it! It’s really easy to make and such a great combo! 😄
10/10? Are you sure? I mean, it’s just chicken and some bread. How can it be THAT good?
I made this and forgot to add the mayo. It still tasted fine but I’m sure it would’ve been better the right way.
Too complicated! I just wanted a quick sandwich. The grilling took forever and my bread burned.
Looks good, but I don’t think there’s enough flavor. Maybe add some chili or something?
I think the seasoning is fine as is, but chili could add a zing! Worth a try!
This was amazing! The flavors worked so well together. I couldn’t get enough!
Yumm! Perfect for lunch. I added some spicy mayo for a kick. Highly recommend!
This sandwich is a game changer! Loved the grilled chicken flavor, so juicy. Definitely making this again!
