Ingredients for Stuffed Pepper Casserole

Here’s everything you’ll need to make my favorite stuffed pepper casserole – I promise it’s all simple stuff you probably already have! The magic is in how these basic ingredients come together.

• The protein: 1 pound ground beef (I use 85% lean – enough fat for flavor but not too greasy)
• The veggies: 1/2 onion (chopped), 1 green bell pepper and 1 red bell pepper (both chopped), 4 cloves garlic (minced)
• The saucy bits: 1 (10-ounce) can diced tomatoes with green chiles, 1 (15 ounce) can tomato sauce
• The spices: 3 tablespoons taco seasoning (your favorite brand), salt and freshly ground black pepper to taste
• The carbs: 1 1/2 cups uncooked long grain rice, 1 cup beef broth
• The cheesy goodness: 4 ounces Colby cheese and 4 ounces pepper Jack cheese (both shredded)

Oh, and don’t forget the nonstick cooking spray – nothing worse than cheese fused to your baking dish!

How to Make Stuffed Pepper Casserole

Okay, let’s get cooking! This stuffed pepper casserole comes together in three simple steps – I promise it’s even easier than trying to wrestle whole peppers into submission. Just follow along and you’ll have dinner bubbling away in no time!

Step 1: Prep and Brown the Meat

First things first – crank your oven to 375°F and grab that trusty 9×13 baking dish. Give it a quick spray with cooking spray so nothing sticks later. Now, heat up your largest skillet over medium-high heat and toss in that ground beef with the onions and peppers. You’ll know it’s ready when the beef loses that pink color and starts getting those delicious crispy brown bits – usually about 7-10 minutes. Pro tip: Drain off any excess grease before moving on unless you want a super-rich (but slightly greasy) casserole!

Step 2: Combine Ingredients

Once your meat mixture is looking good, stir in all those flavorful extras – canned tomatoes, tomato sauce, and that taco seasoning that makes everything better. Now here’s the fun part – dump your uncooked rice right into the baking dish and pour the beef broth over it. Gently fold in the meat mixture with a spatula until everything’s evenly distributed. Don’t overmix though – we want layers of flavor, not mush!

Step 3: Bake to Perfection

Time for cheese therapy! Sprinkle both kinds of shredded cheese evenly over the top – I like to do a little taste test while I’m at it. Cover tightly with foil (this keeps all that steam in to cook the rice perfectly) and pop it in the oven for about 50 minutes. When the timer dings, take off the foil and let it bake another 5 minutes until the cheese gets that gorgeous golden color. Trust me, resisting the urge to dig in immediately is the hardest part!

Tips for the Best Stuffed Pepper Casserole

After making this casserole more times than I can count, here are my can’t-live-without tips:

• Resting is key: Let it sit for 5 minutes after baking – the flavors will settle beautifully and you won’t burn your mouth!
• Taste as you go: Need more kick? Add extra taco seasoning or a dash of cayenne to the meat mixture.
• Cheese flexibility: Out of Colby? Try cheddar. Want it spicier? Use all pepper Jack. Mozzarella makes a great mild option too.
• Rice tip: If your rice isn’t quite tender after baking, just recover with foil and give it 5 more minutes.

Remember – this recipe is super forgiving, so don’t stress!

Stuffed Pepper Casserole Variations

One of the things I love most about this recipe is how easily you can switch things up! When I’m feeling adventurous – or just cleaning out the fridge – here are my favorite twists:

• Protein swaps: Ground turkey works great for a lighter version (add an extra splash of broth to keep it moist)
• Veggie mix-ins: Toss in zucchini or mushrooms when browning the meat, or sub poblano peppers for extra smoky flavor
• Heat lovers: Kick it up with diced jalapeños or a spoonful of chipotle peppers in adobo sauce
• Rice alternatives: Brown rice adds extra fiber (just increase liquid slightly and bake a tad longer)

The possibilities are endless – make it your own! You can find more great recipes here.

Serving Suggestions for Stuffed Pepper Casserole

This casserole is practically a meal on its own, but here’s how I like to round out the plate for those nights when I want to feel fancy:

• Bread basket: Warm garlic bread or buttery cornbread to sop up all those delicious juices
• Fresh crunch: A simple green salad with tangy vinaigrette cuts through the richness perfectly
• Cool contrast: Dollop of sour cream or guacamole on top adds creamy texture
• Mexican twist: Serve with tortilla chips and salsa for a fun fiesta feel

Honestly though? Sometimes I just grab a fork and eat it straight from the pan – no judgment! If you enjoy this style of comfort food, you might also like my hamburger casserole.

Here’s the best part about this stuffed pepper casserole – it actually gets better as leftovers! I always make a double batch because it reheats like a dream. Just let it cool completely, then store it covered in the fridge for up to 4 days. For longer storage, freeze individual portions in airtight containers (they’ll keep beautifully for 2-3 months).

When you’re ready to eat, microwave single servings in 1-minute bursts until heated through. For larger portions, I prefer reheating in a 350°F oven (about 20 minutes covered with foil) to keep that perfect casserole texture. Pro tip: Sprinkle a little extra cheese on top before reheating – it gives that fresh-from-the-oven feel!

Stuffed Pepper Casserole FAQs

I get asked these questions all the time about my stuffed pepper casserole – here’s everything you need to know!

What’s the difference between stuffed peppers and this casserole?
The classic version involves stuffing whole peppers individually – pretty but time-consuming! My casserole gives you all those amazing flavors without the fuss. Instead of stuffing, we mix everything together and bake it in one dish. Same great taste, way less work!

Can I use instant rice instead of regular rice?
You sure can! Just reduce the liquid slightly (about 1/4 cup less broth) and check for doneness after 30 minutes of baking. The texture will be a bit softer, but still delicious.

How spicy is this casserole?
The heat level is totally adjustable! With basic taco seasoning and pepper Jack cheese, it’s got a mild kick – about like a taco. Want it milder? Use Monterey Jack instead. For more heat, add extra taco seasoning or some diced jalapeños when cooking the meat.

Can I make this vegetarian?
Absolutely! Swap the ground beef for plant-based crumbles or lentils, and use vegetable broth instead of beef broth. The flavors still come through beautifully!

Nutritional Information

Okay, let’s talk numbers – but remember these are estimates that can vary based on your exact ingredients! Here’s the breakdown per serving (about 1/8th of the casserole):

• Calories: Around 420
• Protein: 24g (thanks to all that beef and cheese!)
• Fat: 18g (9g saturated)
• Carbs: 38g (with 3g fiber)

Not too shabby for such a hearty, satisfying meal! And hey – those bell peppers totally count toward your veggies for the day. If you want to see more of my family’s favorite recipes, check out our page on Facebook!
