Super easy one-pan Paleo Pesto Baked Chicken that’s kid friendly, Whole30 friendly, healthy and seriously delicious! Ready in 30 minutes and perfect for weeknights.
Little effort, big results. That about sums up this INSANELY delicious, easy Paleo Pesto Baked Chicken! Clearly, I’m on an easy meal kick lately – and I’m not about to stop anytime soon.
I honestly have no clue why it took me so long to break out this old pesto recipe and give it new life. But now that I think of it, I’m sure the answer has something to do with the kids revolting against the GREEN appearance of the pesto when they were toddlers.
We must be making progress though, because each one of them LOVED the pesto and this recipe is now officially in our dinner rotation, along with our bacon wrapped chicken thighs, slow cooker BBQ chicken and meatballs. Lots of chicken happening lately, I must say!

I took my old pesto recipe and revamped it a bit with the addition of baby spinach along with the basil, and nutritional yeast, which I’ve been quite the fan of lately. If you haven’t experimented with nutritional yeast, I highly recommend trying it out with eggs, roasted veggies, or the breakfast casserole I’ve been making lately.

The pesto itself is incredibly easy to make – you just put all the ingredients into a high speed blender or food processor, turn it on, and let the pesto-magic happen. The recipe makes extra pesto to use in another recipe or just to enjoy with whatever you happen to be eating – I especially love it with eggs, potatoes, or as a topping with any of my favorite breakfast hash recipes.
One you make the pesto, you simply top the chicken, layer on sliced tomatoes, sprinkle with a bit of additional spice and then bake for 25 minutes. You can serve it over salad, with roasted veggies or potatoes – you absolutely can’t go wrong with this delicious, savory pesto baked chicken!
I’m all for easy one-pan, oven-baked recipes to make my weeknights easier! One more serious plus to this chicken is how well the leftovers keep.
I actually made the chicken during the day and it stayed perfectly moist and full of flavor for hours, plus survived reheating of the leftovers for lunch the next day. I’m thanking the pesto – which is now in my fridge 24/7 because I’m just a little obsessed with it. Hope you like it – let’s cook!

Easy Paleo Pesto Baked Chicken {Whole30}
Easy Paleo Pesto Baked Chicken {Whole30}

Ingredients
For the Pesto*
- 1 cup raw shelled walnuts
- 3 cups fresh basil leaves
- 2 cups fresh baby spinach leaves
- 4 cloves garlic
- 2/3 cup light flavored olive oil
- 3/4 tsp salt you can adjust to your taste
- 2 tbsp nutritional yeast**
For the Chicken:
- 1.5 lbs organic boneless skinless chicken breasts
- sea salt & pepper
- 4 slices tomato
- generous pinch Italian seasoning I used this one
- generous pinch nutritional yeast**
Instructions
-
First, make the pesto while you preheat your oven to 400 F. You can also make the pesto the day before and store in the fridge to eliminate prep time.
-
Add all of the pesto ingredients to a high speed blender or food processor (I used this one) and process/blend on high speed until a "paste" forms, stopping to scrape the sides and stir once or twice for even blending. Store the pesto in a covered container/jar in the refrigerator for up to one week.
-
Place the chicken breasts in a well greased baking dish or cast iron skillet (I used this one) and sprinkle with salt and pepper. Then, generously spread the pesto all over the chicken (I went VERY generous!) and save the rest for another recipe.
-
Top each piece of chicken with 2 tomato slices and a generous pinch of nutritional yeast** and Italian seasoning.
-
Bake in the preheated 400 F oven for 25-30 minutes or until just cooked through. Slice chicken as desired and serve! Makes 4-6 servings.
Recipe Notes
*This pesto recipe makes more than you'll need for the chicken. Store the remaining pesto in a lidded container in the refrigerator for up to one week.
**You can omit, or you can replace with parmesan cheese if you are okay with dairy and are not completing a Whole30.

I don’t think Ive ever made my own pesto but this looks like its definitely worth trying! Love an easy one-dish meal like this. I could definitely see myself making the pesto over the weekend to save time during the week.
Totally worth trying for how easy it is, and the pesto itself goes with everything!
Thanks for sharing! I have run into trouble finding nutritional yeast at the grocery store. How does it come out without using this ingredient? Thank you!
You lose a little bit of flavor but it’s still very tasty 🙂
I get nutritional yeast in the bulk section – if you have never cooked with it you really should try! It adds a rich, cheesy-like texture!
So easy to make and very delicious!
Yay!
Definitely trying for my Whole30 this month! I don’t know much about the nutritional Yeast…what does that do for the chicken baking process? 🙂
nothing regarding the baking but it adds a subtle “cheesy” flavor to the pesto!
Made this for dinner for my mom the other night along with some roasted potatoes and a big salad and it was SO good!!! We both loved it, and she was surprised the Whole30 meal I made for her could be so delicious 🙂 love the pesto so much, and I’m glad I have a bunch extra. I added some lemon zest & juice to the pesto as well to give a little zip. Thanks for the wonderful Whole30 recipes – you’ve been making Whole30 way easier for me!
That’s awesome Rachel! So happy to hear that! I love having extra pesto leftover to put on everything 🙂 The lemon zest sounds delicious. We’re big fans of your recipes over here as well – my kids ask me to make everything they see of yours on Pinterest!
This recipe is fabulous. Thank you very much for sharing it! I made it for a few friends the other night, and they loved it. The leftovers are great, too.
I made a few small changes to the recipe that worked well for me:
I used pine nuts instead of walnuts because I prefer pine nut pesto.
I cut the amount of garlic and spinach in half.
I butterflied the chicken breasts to make them thinner. I baked the chicken at 400 degrees for 20 minutes, and it was very well done. Next time I’ll probably try baking the chicken for 15-18 minutes.
Thank you again!
This is the best pesto i have ever tasted!! I made it for the spaghetti squash recipe and my husband and I loved it. He said “this is really good” more than once which is unusual lol AND then we used the left over for chicken breast and DELISH! Always going to have this in my fridge!
Can I make it without nuts? My husband can’t eat them.
I do believe you can, however I would add more basil and spinach to make up for some of the lack of bulk.
Can’t wait to try this recipe. For the pesto, is there anything that I can substitute for the walnuts that is not nut based? Thanks!
Hmm, not that I know of so I’m really not sure!
Some people replace nuts with sunflower seeds…..
Great recipe!! It was a easy to make and is one of my new fave weeknight sauces!
This was phenomenal! I like it even better than non-paleo pesto, honestly. It was really packed with flavor. I accidentally used chicken breasts vs. thighs so I had to add baking time but the tomato was a nice touch.
On another note, the meatballs are going on the repeat dinner menu! My husband, who is not paleo, ate all of it. He even put them on a sandwich. Just perfect.
Keep up the good work!
That’s amazing to hear – thrilled you loved it! And the meatballs, too! Love it when the non-paleo family members like the recipes too, then you really know they’re winners 🙂
