Ingredients You’ll Need

To make this flavorful Stuffed Pepper Casserole, gather these simple, everyday ingredients:

• 1 ½ tablespoons olive oil, divided
• 1 ¼ pounds lean ground beef (or ground turkey for a lighter option)
• 1 medium yellow onion, diced
• 1 large red bell pepper, diced
• 1 large green bell pepper, diced
• 3-4 garlic cloves, minced
• 1 teaspoon Italian seasoning
• 1 teaspoon smoked paprika
• 1 teaspoon ground cumin
• 1 teaspoon kosher salt, plus more to taste
• ½ teaspoon ground black pepper
• 2 teaspoons Worcestershire sauce
• 2 tablespoons tomato paste
• 1 can (15 oz) fire-roasted diced tomatoes, with juices
• 1 cup beef broth (or chicken broth)
• 1 cup long-grain white or brown rice, rinsed and drained
• 1 cup frozen chopped spinach, thawed and squeezed dry
• 1 cup shredded cheese (cheddar, mozzarella, or pepper jack)
• Fresh parsley or cilantro, chopped (optional garnish)
• Greek yogurt or sour cream (optional for serving)

Ingredient Notes

• Ground Beef: Lean ground beef gives the casserole a hearty flavor without being too greasy. For a lighter option, substitute with ground turkey or even ground chicken. This is an easy way to turn it into a healthy stuffed pepper casserole without losing taste.

• Rice: Both white and brown rice work well. White rice cooks faster and makes the dish ready in under an hour. Brown rice takes longer but adds more fiber, making the meal more filling. For low-carb diets, you can skip the rice altogether and create a stuffed pepper casserole without rice by using cauliflower rice or extra vegetables. Choosing the best rice for stuffed peppers depends on your cooking time and nutrition goals.
• Bell Peppers: Red peppers are sweet and vibrant, while green peppers have a sharper, slightly bitter flavor. Mixing colors creates a balance of taste and adds visual appeal. Yellow or orange peppers can also be used for a sweeter twist.
• Cheese: Cheddar melts into a sharp, gooey topping, mozzarella brings mild creaminess, and pepper jack adds spice. For best results, shred your own cheese instead of using pre-shredded, which often contains anti-caking agents.
• Canned Tomatoes: Fire-roasted tomatoes add a smoky depth that enhances the casserole’s flavor. Regular diced tomatoes work fine too, but fire-roasted is the best choice if you want that extra layer of taste.

How To Make Stuffed Pepper Casserole (Step-by-Step Instructions)

Making this hearty Stuffed Pepper Casserole is simple, quick, and rewarding. Each step builds flavor and brings the dish together into a comforting one-pan meal that is perfect for any night of the week. Follow these directions for the best results.

Detailed Instructions

Step 1: Brown the Ground Beef (or Alternative)

Heat one tablespoon of olive oil in a large skillet over medium heat. Add the lean ground beef and cook until it browns, breaking it into small pieces with a wooden spoon. Browning the meat first gives the casserole a rich flavor base. If you want a lighter option, ground turkey or chicken also works well. For a vegetarian stuffed pepper casserole, you can skip the meat and start with beans or lentils instead. Once cooked, remove the meat and set it aside.

Step 2: Sauté the Veggies

Add the remaining olive oil to the same skillet. Toss in the diced onion and colorful bell peppers. Cook for about 4 to 5 minutes until softened. The peppers release sweetness as they cook, and the onion adds a savory base. Using a mix of red and green peppers creates a balance of flavors and keeps the dish bright and appetizing.

Step 3: Add Spices, Tomato Paste, and Diced Tomatoes

Stir in the garlic, Italian seasoning, smoked paprika, cumin, salt, and pepper. Cook for one minute to let the spices bloom, releasing their full aroma. Add tomato paste and stir well, letting it caramelize slightly to deepen the flavor. Then pour in the fire-roasted diced tomatoes with their juices. This step layers the dish with smoky, tangy notes that are essential for a bold stuffed pepper casserole.

Step 4: Add Rice and Broth

Mix in the rinsed rice, whether you choose white for a quicker cook time or brown for extra nutrition. Pour in the beef broth, or use chicken broth for a lighter taste. Stir everything well, then bring the mixture to a boil. Once it boils, reduce the heat to low, cover, and let it simmer. White rice will take about 20 to 25 minutes, while brown rice needs 35 to 40 minutes. For a stuffed pepper casserole without rice, swap in cauliflower rice and reduce the broth slightly.

Step 5: Combine and Bake

When the rice is tender and most of the liquid has been absorbed, stir the cooked ground beef back into the skillet. Add in the thawed spinach for a boost of color and nutrients. Mix everything until it is well combined. At this point, you can continue on the stovetop or transfer the mixture into a casserole dish for baking. Bake at 375°F for about 10 minutes to let the flavors meld.

Step 6: Top with Cheese

Sprinkle shredded cheese evenly across the top of the hot casserole. Cheddar gives it a sharp, gooey finish, while mozzarella melts into a creamy layer. Pepper jack adds a little kick if you like spice. Cover the skillet or dish for 2 to 3 minutes, or return it to the oven until the cheese is fully melted and bubbling. This step transforms the casserole into a true comfort food classic.

Step 7: Serve

Once the cheese has melted, remove the dish from the heat and garnish with fresh parsley or cilantro. Serve hot, straight from the pan, with a dollop of Greek yogurt or sour cream for extra creaminess. This easy stuffed pepper casserole makes six hearty servings and pairs beautifully with a simple green salad or crusty bread. It is quick, flavorful, and perfect for family dinners or meal prep.

Pro Tips for the Perfect Stuffed Pepper Casserole

Making the best stuffed pepper casserole is all about paying attention to the small details. These simple tips and tricks will help you get a flavorful, perfectly textured dish every time.

• Brown the meat well:
  Take time to brown the ground beef instead of rushing. Cook it over medium heat until it develops a golden crust. This caramelization adds depth and prevents the casserole from tasting flat. If you use ground turkey or chicken, add a splash of olive oil to keep the meat juicy.
• Control the rice texture:
  To avoid soggy rice, always rinse it before cooking to remove excess starch. Make sure you measure the broth correctly and keep the pan covered while it simmers. Resist the urge to lift the lid often, as this lets out steam and slows the cooking process. For firmer texture, use long-grain rice instead of short-grain.
• Layer the flavor:
  Cook the spices with the garlic and tomato paste before adding the tomatoes. This quick step wakes up the seasoning and makes the casserole taste richer. Fire-roasted diced tomatoes are ideal for boosting flavor, but you can add a pinch of sugar if you use regular tomatoes to balance acidity.

• Finish strong:
  Always top with freshly shredded cheese, not pre-packaged, for the smoothest melt. Let the casserole rest for a few minutes before serving so flavors settle and slices hold together better.

With these pro tips, you’ll turn a simple recipe into the best stuffed pepper casserole that your family will ask for again and again.

Recipe Variations

One of the best parts of this dish is how easy it is to adapt. Whether you follow a plant-based diet, avoid gluten, or skip dairy, there is a version of Stuffed Pepper Casserole for you. Below are four delicious variations that make this recipe work for every lifestyle.

Vegetarian Stuffed Pepper Casserole

For a hearty vegetarian stuffed pepper casserole, replace the ground beef with a mix of black beans, lentils, or chickpeas. These plant-based proteins hold up well and add satisfying texture. Use vegetable broth instead of beef broth, and keep the same seasoning blend for bold flavor. This version is filling, high in fiber, and perfect for meatless Mondays.

Vegan Stuffed Pepper Casserole

To make a vegan stuffed pepper casserole, follow the vegetarian steps but skip the cheese. Instead, use shredded vegan cheese that melts well, such as cashew- or coconut-based varieties. You can also sprinkle nutritional yeast into the mixture for a nutty, cheesy flavor. Top with fresh avocado slices or dairy-free sour cream for a creamy finish.

Gluten-Free Stuffed Pepper Casserole

This dish is naturally gluten-free if you choose the right ingredients. For a gluten-free stuffed pepper casserole, double-check that your broth and Worcestershire sauce are certified gluten-free. Stick with rice or use quinoa as an alternative base. Everything else in the recipe, from the peppers to the tomatoes, is naturally gluten-free, making this an easy switch for sensitive diets.

Dairy-Free Stuffed Pepper Casserole

Cheese is a classic part of the recipe, but it is simple to adapt. For a dairy-free stuffed pepper casserole, swap the shredded cheese with dairy-free cheese alternatives or leave it off completely. To keep the creamy texture, top the casserole with mashed avocado or a drizzle of tahini before serving. Greek yogurt or sour cream toppings can be replaced with coconut-based or soy-based options.

These creative variations ensure that everyone can enjoy the comfort of a one-pan casserole. Whether you need a vegetarian stuffed pepper casserole full of plant protein or a dairy-free stuffed pepper casserole with creamy toppings, there is a version that will fit your table and taste.

What to Serve with Stuffed Pepper Casserole

This hearty Stuffed Pepper Casserole pairs well with light and fresh sides that balance its rich, cheesy flavor. A crisp garden salad with cucumbers, tomatoes, and a tangy vinaigrette adds freshness to every bite. Garlic bread or warm dinner rolls are great for soaking up the flavorful sauce. For extra veggies, try roasted broccoli, green beans, or a simple side of sautéed zucchini. If you want something heartier, serve it with a small bowl of soup like tomato basil or vegetable soup. Together, these sides make the meal complete, turning this casserole into a cozy, family-friendly dinner everyone will love.

Storage and Freezing Instructions

Knowing how to store stuffed pepper casserole the right way keeps it tasting fresh for days. Leftovers are perfect for busy weeks, and this dish is just as delicious when reheated.

• Refrigerator storage:
  Allow the casserole to cool completely before storing. Transfer leftovers into an airtight container and refrigerate for up to 4 days. This keeps the rice firm and the flavors well balanced.
• Freezer storage:
  If you want to save it longer, here’s how to freeze stuffed pepper casserole. Portion the casserole into freezer-safe containers or wrap it tightly with foil and place it in a freezer bag. It can be frozen for up to 3 months. For best results, freeze before adding the cheese topping, then add fresh cheese when reheating for a creamy finish.
• How to reheat:
  For the oven, place the casserole in a baking dish, cover with foil, and heat at 350°F until warmed through, about 20 minutes. This method keeps the texture closest to fresh. For a quicker option, use the microwave. Heat leftovers in a microwave-safe dish, covered, for 2 to 3 minutes, stirring halfway through to ensure even warming.
• Freezing tip:
  Always label your containers with the date so you know how long they’ve been stored. Thaw overnight in the refrigerator before reheating to prevent mushy rice and to keep the flavors intact.

With these storage methods, you can enjoy stuffed pepper casserole any night, without extra work.
