Ingredients in Chicken and Peppers Casserole
- chicken breasts - skinless, boneless chicken thighs may be substituted if you prefer.
- olive oil - vegetable oil or canola oil may be used
- seasoning blend - garlic powder, onion powder, dried minced onion, smoked paprika, ground cayenne pepper, ground black pepper.
- sweet bell peppers - I used red peppers and yellow bell pepper because I liked the colors. Use whatever color you have or is on sale at the grocery store.
- sweet onion - yellow onion, red onion or white onion will work if that’s what you have on hand.
- cream cheese - I used full fat cream cheese
- shredded cheese - I used Colby Jack, but any of your favorite cheeses can be used.

Tips and Recipe Variations
- Use whatever kind of bell peppers you have around. Green bell peppers are usually the least expensive in the grocery store.
- You can use the cheese mixture of your choice. I would suggest a mozzarella, cheddar, a mixture of gouda and mozzarella or if you want to add a little spice add some Monterey Jack. Picky eaters? Mozzarella cheese is your go-to.
- If you can find the time to shred the cheese yourself (I know, it’s such a drag but I'm cheering for you!…), it really melts waaaaay better than pre-shredded cheese. That being said, you can use a bag of pre-shredded cheese in a pinch.

Baked Chicken and Peppers recipe for two
This recipe is made to serve 8. To make a smaller portion, I recommend you cut the recipe in half. Freeze half the recipe for another meal, or cook the recipe as is for 4 servings.
Other shortcuts you'll find useful are to use a teaspoon of taco seasoning or fajita seasoning in place of the spice blend.
You can vary the leftovers by changing up the side (pasta, rice, etc) and use the other half as a salad topping.
Recipe Shortcuts
For easiest chicken prep, you can opt to use chicken tenderloins. Half of the chopping is already done for you and you just need to cube them.
Save This Recipe For Later
You can substitute the seasoning with 2 tablespoons of taco seasoning or a fajita spice blend.
Check out your produce aisle for pre-cut peppers and onions to save a step.
To Make as a Freezer meal
You can prepare this meal ahead of time.
In a plastic bag mix chicken, oil, spices, peppers, and onions. Take as much air out as possible. Massage the bag so the chicken and veggies get coated and place in the fridge until ready to use. You can also freeze the bag and use it within 2-3 months. Thaw in the fridge overnight.

How to meal prep this ahead of time:
Cut the chicken into bite size pieces and store in a large mixing bowl in the refrigerator along with the cut peppers and onions. I know the recipe card has this in two steps but I'm giving you permission to break the rules!
Mix the seasoning blend in a small bowl and set aside
What to serve with Baked Chicken and Peppers
Serve this alongside your favorite rice side, pasta, or cauliflower rice. A side salad is nice, too!
Or, turn these into flour tortilla wraps or use a whole grain wrap. Hello, field meal!
How to store leftovers
Store leftovers in an airtight container for 2-3 days.

Made this according to your recipe and my strapping 21 yo son exuberantly stated this was delicious and ‘restaurant quality’, haha, which I suppose is high praise for a wholesome homemade dinner with no seed oils or cheap ingredients! Thanks for the creative meal recipe!

Delicious! I did not cube my chicken; instead I mixed the cream cheese with dried thyme, salt, pepper, and minced garlic. Then, stuffed it inside the butterflied chicken breasts. I did have to cook longer but had a thermometer so that wasn't a problem. I seasoned as recommended but browned the chicken before putting it in the oven. Finally, I put slices of pepper jack cheese on top. So, you can't go wrong with this recipe. I'm sure it would have been just as good if I followed exactly.
Angela says
This was delicious! The only thing I added was two cloves of garlic. Instead of the seasonings listed, I used taco seasoning and Lowry’s. I served it with yellow rice and jalapeño pinto beans, fresh jalapeños and cilantro. So good!

I DON'T HAVE CREAM CHEESE. I HAVE RANCH DRESSING, CAN THAT BE A SUBSTITUTE?
