One dish dinners

This is one of those recipes you should definitely keep in your back pocket for the nights your body wants to order takeout but your brain is like, “JUST MAKE DINNER.”

If you have some pesto in your freezer or pantry (I make my Whole30 Dairy-Free Pesto in large batches and freeze it), this recipe requires almost no prep time at all. Just slice the tomatoes, quickly assemble it, and stick it in the oven.

All the recipe ingredients labeled on a white marble board.

Recipe Ingredients

Have you ever seen a shorter list of ingredients? Yeah, me neither.

  • Chicken Breasts
  • Olive Oil
  • Pesto (Use my Dairy Free Pesto recipe to stay Whole30 compliant, or grab your favorite store-bought brand)
  • Roma Tomatoes

I like to serve Pesto Baked Chicken with a side of Keto friendly sautéed spinach or spaghetti squash.

Step by Step Process Shots showingng how the dish is assembled - first the oil is spread on the bottom of the dish, then the chicken, then the pesto, then the sliced tomatoes.

How to Make It:

  1. Drizzle olive oil on the bottom of the 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, you could layer 1 cup of shredded full fat mozzarella cheese – However this would NOT be Whole30 or Paleo compliant.
  4. Arrange the tomato slices on top and bake!

Ingredients

Pesto Baked Chicken

  • 2 lbs chicken breasts

  • 2 tbsp fresh basil
  • salt and pepper to taste

Dairy Free Pesto

    Instructions

    Prepare the Dish

    1. Preheat your oven to 375F. Slice your tomatoes into 1/2 inch slices, then set them aside.

    2. Gently pound each breast to a uniform thickness. Pat the chicken dry with a paper towel, and lightly season with salt and pepper.

    3. Drizzle oil on the bottom of the baking dish.

    4. Lay the chicken breasts inside the baking dish. Note: It's okay if they're squished and overlapping a little as they'll shrink while they cook, just don't arrange them in a tall heap.

    5. Spoon the pesto on top of the chicken and spread it evenly.

    6. Arrange the sliced tomatoes on top of the pesto.

    Cook & Serve the Dish

    1. Transfer to the oven and bake for 25 minutes. Remove from the oven, and allow to cool slightly.

    2. Sprinkle the dish with fresh basil leaves and black pepper.

    3. Serve with sauteed spinach or spaghetti squash.

    Recipe Notes

    Note: This dish can be prepared the night before you plan to cook it. Layer the chicken, pesto, and tomatoes in the baking dish, then cover tightly with foil or plastic wrap. Set it in the refrigerator until you’re ready to cook it.
