Colorful bell peppers packed with a fragrant, nutty wild rice filling make for a comforting and visually stunning vegetarian centerpiece. Sweet bell pepper cavities are loaded with a savory blend of wild rice, tender cremini mushrooms, sweet corn, black beans, aromatic herbs, and melted sharp white cheddar cheese, then baked until the pepper walls become tender and sweet.
The secret to perfectly cooked stuffed peppers is Pre-Baking the Empty Pepper Halves Covered with Foil for 15 Minutes Before Stuffing. Raw bell pepper walls are thick and take longer to cook than the filling; pre-baking ensures the peppers turn tender and sweet without overcooking or drying out the grain filling inside.

Step-by-Step Instructions
1.Pre-Bake the Empty Bell Peppers:15 min.
Preheat your oven to 375°F (190°C). Slice 4 large bell peppers in half lengthwise through the stem and scoop out the seeds and membranes. Place the pepper halves cut-side up in a 9×13-inch baking dish. Drizzle the insides with 1 tablespoon olive oil, sprinkle with ¼ teaspoon salt, and pour ¼ cup of water into the bottom of the dish. Cover tightly with foil and bake for 15 minutes to soften.
2.Cook the Wild Rice Blend:40 min.
In a saucepan, bring 1 cup of wild rice blend and 2 cups of vegetable broth to a boil. Reduce heat to low, cover, and simmer for 35 to 40 minutes until the grains are tender and split open. Remove from heat, let stand covered for 5 minutes, then fluff with a fork.
3.Sauté the Mushroom & Herb Filling:8 min.
Heat 2 tablespoons olive oil in a skillet over medium heat. Add 1 finely diced yellow onion and 8 oz finely chopped cremini mushrooms; cook for 6 minutes until browned and moisture evaporates. Stir in 3 minced garlic cloves, 1 teaspoon fresh thyme leaves, 1 teaspoon smoked paprika, ½ teaspoon salt, and ¼ teaspoon black pepper; cook for 1 minute until fragrant.
4.Combine Rice, Beans & Cheese:3 min.
In a large bowl, combine the cooked wild rice, sautéed mushroom mixture, 1 can (15 oz) drained rinsed black beans, 1 cup sweet corn, ½ cup tomato sauce, and 1 cup shredded sharp white cheddar cheese. Stir thoroughly to combine.
5.Stuff, Top & Bake:20 min.
Remove foil from the pre-baked peppers and drain any excess water inside the cavities. Generously mound the wild rice filling into each pepper half. Top with another ½ cup of shredded cheese. Bake uncovered at 375°F (190°C) for 15 to 20 minutes until the peppers are completely tender and the cheese is melted and golden. Garnish with fresh chopped parsley or cilantro!
Expert Tips for Success
- Cook Rice in Vegetable Broth: Cooking wild rice in seasoned vegetable broth instead of plain water infuses rich flavor into every grain from the inside out.
- Slice Peppers Lengthwise: Slicing peppers from stem to base creates boats that are easier to fill, cook faster, and sit flat in your baking dish compared to cutting off the tops.
- Use Finely Diced Mushrooms: Chopping mushrooms down to the size of rice grains allows them to blend seamlessly into the wild rice mixture while adding savory umami depth.
