Hello one dish dinner! This simple budget-friendly Pesto Baked Chicken recipe is a family favorite, made with just one baking dish and a few simple ingredients… all in under 30 minutes! Best of all, it’s completely Paleo, Whole30, Dairy Free, Low Carb, and Keto friendly.

Easy One Dish Dinner

This Baked Pesto Chicken recipe is definitely one of those recipes you should definitely keep in your back pocket for busy weeknights. There are so many evenings my body wants to order takeout but your brain is like, “JUST MAKE DINNER.” When that happens, this is the recipe to make!

It’s so easy that it’s almost a no-cooking-required recipe! If you have some pesto in your freezer or pantry (I make my Dairy-Free Pesto in large batches and freeze it), this recipe requires pretty much no prep time at all!

All you need to do to make it is slice the tomatoes, quickly assemble the ingredients in a dish, and stick it in the oven. While it cooks, I like to make myself a quick mocktail and sit my booty on the couch for a minute.

Recipe Ingredients

This is what you’ll need to make this recipe at home. Have you ever seen a shorter list of ingredients? Yeah, me neither.

  • Chicken Breasts. Use plain chicken breasts or for extra oomph, use my Pesto marinated chicken breasts!
  • Olive Oil or avocado oil.
  • Pesto: Use my Dairy Free Pesto recipe to stay Whole30 compliant, or grab your favorite store-bought brand, whatever you prefer!
  • Roma Tomatoes.
  • Mozzarella cheese, optional. The cheese is Keto friendly but not Whole30 or Paleo. Use it or not, whichever you prefer!

Optional: I like to serve Pesto Baked Chicken with a side of Keto friendly sautéed spinach, cauliflower mash, or spaghetti squash.

How to Make It

I told you it was easy, didn’t I? Just follow these step by step instructions to make it at home!

  1. Drizzle the olive oil on the bottom of an oval or square baking dish.
  2. Add the chicken breasts. It’s okay if they’re smooshed in a little bit, because they’ll shrink as they cook — just don’t pile them up into a stack.
  3. Spread the pesto evenly over the top of the chicken breasts.
    *Optionally, if you’re eating Keto and decide you’d like to add mozzarella cheese to the dish, sprinkle 1 cup of shredded full fat mozzarella cheese on top of the pesto. Remember, this would NOT be Whole30 or Paleo compliant.
  4. Arrange the tomato slices in rows on top of the chicken, set in the oven, and bake!

Once it comes out of the oven, give it a little sprinkle of fresh basil and salt and pepper and serve. It’s fabulous on its own or with whatever side dishes you like. That’s it!

  • Arrange the sliced tomatoes on top of the pesto.

    We absolutely LOVE this recipe! Our only hitch (and I would love to hear your thoughts) is that is always, every single time, takes about twice the time to cook. I’ve tried it in 2 different ovens, and both times it took at least double the time at the given temperature. I’ve tried raising the temp, and that risked drying it out more. We love the flavors and the final result, but it seems to cook much slower that the recipe calls for.
    Thank you for posting this!

    1. Hi Bonny! I’m so glad to hear you enjoy the dish! I’m a little stumped about the cook time, too! My first thought is that you could be using larger chicken breasts than I used, but it might also make sense to double check the internal temperature of the chicken for doneness (165F at the thickest part). I’ll look back over my notes next time I make this at home and see if I can come up with any other possibilities, and please let me know if you get to the bottom of it on your end! Thanks again for your kind feedback!! -Laura
