Why We Love This Recipe

Stuffed Peppers are a go-to for us and this great variation has a yummy tex-mex flavor!

This casserole is quick and easy to put together. Prep only takes minutes, and using instant rice means it cooks fast!

Extra ingredients (and veggies) can be added to stretch this dish even further. Corn, black beans or pinto beans, or zucchini (or even extra peppers) are all good choices.

Ingredients/Variations

Stuffed Pepper Casserole only uses a handful of ingredients!

MEAT This recipe uses ground beef with Homemade Taco Seasoning. Ground chicken, ground turkey or shredded rotisserie chicken would taste great too!

VEGGIES Fresh bell pepper, onion, and tomatoes are loaded into this casserole. Feel free to add corn, jalapenos or some beans to stretch this dish even further!

RICE Instant rice is the perfect addition to this casserole! Out of instant rice? To use long-grain white rice, cook the rice in broth on the stove according to package directions or use leftover rice. If using cooked rice, do not add broth to the casserole. Try tomato basil rice for a delicious twist!

CHEESE This casserole is topped with cheddar cheese, but any cheese will taste great. Use Tex-Mex or Monterey Jack for an extra kick!

VARIATIONS Want more spice? Add some chili powder or try swapping the tomato sauce for homemade enchilada sauce!

  1. I RARELY leave comments because, quite frankly, I’m too busy stuffing my face with Holly’s recipes! This recipe, since first est. early 2024 in this house, has become hands down in the weekly rotation.
    I use this recipe and add a TBSP of Cumin to put a slight twist (sort of like the Taco Pepper Casserole Holly has!)!!!
    This recipe is also fail proof!
    Nice work, Holly! Very nice!5 stars

    1. Oh my gosh, Valarie! You are too sweet. I am so glad you are enjoying our recipes. ❤️

  2. Probably a great recipe as is, but I’m posting because I used cooked rice and these were my notes that I thought might be helpful for those who also might need to improvise. Not having pre-cooked the peppers and onions (I had large green onions) they cooked fine. I covered casserole and cooked until it was bubbly which was 15 minutes for me. I don’t think cooking for 30 minutes with cooked rice is necessary, but ovens do vary. I had large softball-sized peppers and I thought two was enough to get some peppers in each bite. I also subbed a smaller 10oz a of rotel tomatoes and didn’t feel like it was lacking. Lastly I added more cumin, garlic, onion, and chili powders to taste because I like strong flavors when I’m pregnant, but otherwise wouldn’t need it. ;)5 stars
