Stuffed Pepper Casserole Ingredients
The full ingredients list with measurements is listed in the printable recipe card at the bottom of the post.
- Olive Oil.
- Ground Meat. I'm using ground beef, though you can also use ground turkey, chicken, pork, sausage, tofu, or other similar.
- Vegetables. Onion, bell peppers (use any color – green bell peppers, yellow, red, orange), jalapeno pepper (optional, for spicy), garlic.
- Fire Roasted Tomatoes. Canned is great. Or you can use diced tomatoes or tomato sauce.
- Worcestershire Sauce.
- Seasonings. Paprika, dried oregano, basil, salt and pepper to taste. You can easily vary this up to your personal favorites, like Italian seasonings or Cajun seasonings.
- Cooked Rice. White rice, brown rice, or wild rice.
- Melty Cheese. Use cheddar cheese, mozzarella, or a blend – I LOVE pepperjack for myself.
- For Garnish. Fresh chopped parsley, red pepper flakes.
How to Make Stuffed Pepper Casserole - the Recipe Method
Prep Oven. Preheat your oven to 425°F (220°C).
Cook the Vegetables. Heat the oil in a large pan or Dutch oven to medium heat and add the onions, jalapeno (if using), and bell peppers. Cook for 10 minutes to soften, stirring often.
Add the garlic and cook 1 minute, or until the garlic becomes fragrant.
Ground Meat. Add the lean ground beef and cook 5-6 minutes, breaking apart as you go, until cooked through.
Prep for Baking. Add the fire roasted tomatoes, Worcestershire sauce, seasonings, and cooked rice. Stir together and remove from heat.
Stir in 1/2 cup of the shredded cheese until incorporated.
Transfer to a casserole dish or baking dish (or keep in the Dutch oven or other oven safe pan).
Top with the remaining shredded cheese.

Bake the Casserole. Bake the casserole for 15-20 minutes, or until the cheese is nice and bubbly.
Cool slightly, garnish, and serve.
Boom! Done! Your stuffed pepper casserole is ready to serve. Easy enough to make, isn't it? This is a great weeknight meal for the whole family. I hope they love it!

Recipe Tips & Notes
- Using cooked rice is a big time saver. However, if you'd prefer to make this dish with uncooked rice, add it at the same time you add the tomatoes, but add 2 cups water, beef broth, or stock, then bake 30-40 minutes, or until the rice is tender and cooked to your preference.
- Let your imagination run wild with variations like Italian Stuffed Peppers, Mexican Stuffed Peppers, or Greek Stuffed Peppers. So many possibilities.
Storage & Leftovers
Stuffed pepper casserole will last up to 5 days in the refrigerator in a sealed container. You can heat it up in a pan in the oven or stove top to enjoy again.
You can also freeze it for 2-3 months.

This is the recipe that keeps on giving! After I ate a couple of days of just the casserole, then I tried leftovers with Susan's idea of nachos. I agree with her - the best nachos ever! But then I went one step further and used the remaining casserole to stuff sweet banana peppers covered with cheddar cheese and candied jalapenos. OMG - your recipes have changed my culinary life, Mike 🙂
Mike Hultquist says
Wow, BOOM! This is so awesome to hear, Donna! I love the creative ways you're enjoying this! Nice!
Fiona says
I tried this recipe and it was gorgeous and all the family loved it! I used a combination of mature white cheddar and mozzarella cheese. I also added a tin of chilli beans to the dish and some extra rice then to balance out the liquid. This will be a new favorite in my house for definite! Thanks Mike
Mike Hultquist says
Great! Glad you enjoyed it, Fiona. I love the addition of the beans.
Rock says
Kinda disappointed with this recipe,seemed to lack a lot of flavor.maybe drain ground beef?used a jalapeño ,and made the recipe as written.no heat and no flavor.
Mike Hultquist says
Rock, sorry it wasn't to your like. It's a good idea to taste and adjust as you go along with cooking. At the simmering stage, you would have probably realized you could use more spices, and could have added more paprika, maybe a touch of cayenne or some hot sauce. Also, some jalapenos can vary in heat. Next time, try a serrano (or 3) or your favorite hot pepper to achieve a heat/flavor level you prefer. Consider this a simple base recipe. Many ways to adjust it next time. Best.
Linda Gross says
Fantastic recipe. I did half the recipe. Thank you.
I used Basmatti rice cooked in vegetable broth, 96% lean fresh ground beef, portobello mushrooms, lots of Italian seasoning, bell and Aleppo peppers, used blend of Mexican Cheese with extra cheddar added to it. Plus all the other ingredients. If I had some fried bacon to crumble in it , that would have put it over the top. I loved that it is quick, easy, cooked in cast iron X-Large Skillet/ One pot!
Mike Hultquist says
Sounds wonderful to me, Linda! Boom!
Cheryl says
I love your recipes Mike! We have an assortment of peppers from our garden I would like to use for this one. What would be the approximate amount of cups worth to use? Thanks!
Mike Hultquist says
Thanks, Cheryl. This is a really forgiving recipe, so you could use more or less, but I would say about 2 cups chopped. You can definitely use a bit more. Enjoy!
Cheryl says
Thank you Mike, this recipe was amazing! Talk about a flavor explosion! I used lipstick peppers (the reason for cup conversion), Anaheim's (what do you do with all of them) and jalapenos. Roasted up some of our garden tomatoes (again, an abundance), but otherwise followed the recipe. Once again a winning meal!
Mike Hultquist says
Boom! Glad you enjoyed it, Cheryl! I appreciate the comments! Thanks for sharing. =) =)
Donna says
The peppers are really producing in my garden, so I made this last night. I used three bell peppers and two hot Hungarian wax peppers, and the heat was perfect for me, although probably too spicy for many people. I used pepper-jack cheese, although it would have been really good with cheddar as well. This had all the flavor of my favorite stuffed green peppers but was easier to prepare. Yet another winner from Chili Pepper Madness. Thanks, Mike!!!
Mike Hultquist says
Awesome to hear, Donna! I love the pepper combination. Glad you enjoyed it!
Susan George says
I made this today and it was SO good! Tomorrow I’m going to make nachos with what’s leftover. I can hardly wait! Thank you for this recipe, it’s a keeper.
Mike Hultquist says
Nice! I love the nachos idea! I appreciate it, Susan. =)
Susan George says
The nachos were our favorite we ever had! I also added some pickled jalapeños. You would love it!
Mike Hultquist says
Perfection! Thanks, Susan.
