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.

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 paste for homemade enchilada sauce!

  1. “We” haven’t tried your recipes yet but each one I’ve printed out looks so delicious and easy. You see I have to live in a Nursing Home now and what I like best about your site I can add how many people will be fed and all the ingredients are adjusted to the recipe. None of the other Recipe sites has that option. So I’m praying that the kitchen will use your recipes because we are tired of having the same food over and over again. If they do, I’ll be back to get more recipes. Thank you so much for adding that extra option of how many people to feed along with the adjusted ingredients to go with it!!

  2. We loved the casserole! Very yummy! I added a jalapeño pepper and a can of black beans! Thanks for a wonderful recipe! I love your website!
