How to Make Pioneer Woman Stuffed Pepper Casserole

Step 1: Preheat the oven

Preheat the oven to 350°F (175°C). Warming the oven early avoids temperature drops when the casserole goes in and ensures even baking.

Step 2: Brown the ground beef

In a large skillet, brown the ground beef over medium heat. Break it up with a spatula and cook until no longer pink (about 6–8 minutes). Tip: Drain excess fat if your beef is less lean to prevent a greasy casserole.

Step 3: Sauté onions and peppers

Add diced onions and bell peppers to the skillet and sauté until softened, about 4–6 minutes. Cook until onions are translucent and peppers begin to release their juices for maximum flavor.

Step 4: Add stock and tomatoes

Stir in the beef stock and diced tomatoes, bringing to a simmer. Scrape up any browned bits from the skillet bottom those are flavor gold. Reduce by a few minutes so the mixture is saucy but not soupy.

Step 5: Transfer and bake

Transfer the mixture to a casserole dish and bake in the preheated oven for about 30–40 minutes until heated through. If you like a slightly drier top, bake uncovered; for a saucier finish, cover for the first 20 minutes, then uncover.

Step 6: Serve hot

Serve hot. Spoon portions onto plates or let diners help themselves family-style. Garnish with fresh chopped parsley or shredded cheese if desired.
