Step‑by‑Step Instructions for Easy Pioneer Woman Stuffed Pepper Casserole

Step 1: Preheat the Oven and Prepare Skillet
Begin by preheating your oven to 350°F (175°C). While the oven warms up, heat a drizzle of olive oil in a large oven-safe skillet over medium-high heat. You’ll know the oil is ready when it shimmers lightly in the pan. This will create a perfect base for your savory Stuffed Pepper Casserole.

Step 2: Brown the Ground Beef
Add the lean ground beef to the hot skillet and break it into chunks with a wooden spoon. Cook for about 5-7 minutes, stirring occasionally, until the meat is browned and fully cooked. You can tell it’s done when there is no pink remaining, and the beef sizzles invitingly. Drain any excess grease if necessary.

Step 3: Sauté the Vegetables
Toss in the diced yellow onion, red bell pepper, and green bell pepper to the cooked beef. Sauté the mixture for about 5-7 minutes until the vegetables soften and the onions become translucent. You should start to smell the amazing aromas coming together, creating the perfect foundation for your Stuffed Pepper Casserole.

Step 4: Add Garlic and Seasonings
Stir in the minced garlic and cook for an additional minute, allowing the garlic to become fragrant. Next, add the Italian or Cajun seasoning, Worcestershire sauce, salt, and ground black pepper to the mixture. Mix everything well to ensure the flavors meld beautifully, making your casserole irresistibly savory.

Step 5: Incorporate the Tomatoes and Rice
Pour in the undrained canned diced tomatoes, uncooked long grain white rice, and beef broth into the skillet. Stir the mixture thoroughly, ensuring the rice is evenly coated. Bring the entire mixture to a gentle boil over medium heat. You’ll see bubbles forming, indicating that it’s time for the next step.

Step 6: Simmer the Casserole Mixture
Once boiling, reduce the heat to low and cover the skillet tightly with a lid. Let it simmer for about 20 minutes, allowing the rice to absorb most of the liquid. Keep an eye out for billowing steam escaping the lid, and make sure the rice is tender and fluffy when uncovered.

Step 7: Transfer and Add Cheese
If necessary, transfer the mixture to a greased baking dish for even baking. Sprinkle a generous layer of shredded cheese over the top. The cheese will melt and create a deliciously gooey topping that adds to the charm of your Stuffed Pepper Casserole.

Step 8: Bake to Perfection
Place the dish in the preheated oven and bake for 25 minutes, or until the cheese is golden and bubbly. You’ll know it’s done when the cheese is irresistibly melted and a delightful aroma fills the kitchen.

Step 9: Rest and Garnish
Once out of the oven, let the casserole rest for about 5 minutes before serving. This allows the flavors to settle beautifully. Garnish with fresh parsley for a pop of color and serve this comforting Stuffed Pepper Casserole at your family dinner table.

Make Ahead Options

This Easy Pioneer Woman Stuffed Pepper Casserole is perfect for meal prep enthusiasts! You can prepare the entire casserole up to 24 hours in advance by assembling it in your baking dish, covering it tightly, and refrigerating it until you’re ready to bake. To maintain quality, store it in an airtight container; this prevents drying out and maintains flavor. When ready to enjoy, simply preheat your oven to 350°F and bake the casserole directly from the fridge for about 30-35 minutes, or until heated through and the cheese is bubbling. This time-saving strategy lets you enjoy a homemade meal without the last-minute stress!

What if my rice doesn’t cook properly in the casserole?
Very common! If you find your rice isn’t cooking evenly, it might be because the skillet wasn’t covered tightly enough during simmering.
