Stuffed Bell Peppers with Ground Turkey, Quinoa & Veggie-Packed Tomato Sauce

Lean ground turkey and protein-rich quinoa are baked into sweet bell peppers with a veggie-forward tomato sauce for a high-fiber, nutrient-dense dinner that still feels cozy and hearty.

Ingredients

• 4 large bell peppers (any color)
• 1 lb lean ground turkey (93–99% lean)
• 1 cup dry quinoa, rinsed well
• 2 cups low-sodium chicken broth or water
• 1 medium yellow onion, finely diced
• 2 medium carrots, finely diced
• 2 stalks celery, finely diced
• 3 cloves garlic, minced
• 1 (14.5 oz) can diced tomatoes (no-salt-added if possible)
• 2 tbsp tomato paste
• 1 tsp dried oregano
• 1 tsp ground cumin
• 1 tsp smoked paprika
• 1/4 tsp red pepper flakes (optional)
• 1 tsp kosher salt, plus more to taste
• 1/2 tsp black pepper
• 1 tbsp olive oil
• 1/2 cup shredded part-skim mozzarella (optional but great for a melty top)
• 2 tbsp chopped fresh parsley or cilantro (optional, for finishing)
• 1/2 cup water (for the baking dish, to help steam the peppers)

Method

• 1

  Step 1: Heat oven & prep peppers

  Preheat oven to **400°F**. Slice the tops off the bell peppers and remove seeds and ribs. If needed, shave a tiny bit off the bottom so they stand upright (don’t cut through). Arrange peppers cut-side up in a **9x13-inch** baking dish.

  Step 2: Par-bake to soften

  Add **1/2 cup water** to the baking dish (around the peppers, not inside). Cover tightly with foil and bake **15 minutes** to jump-start softening so the finished peppers turn tender, not crunchy.

  Step 3: Cook quinoa

  While peppers bake, bring **2 cups broth/water** to a boil in a medium saucepan. Add **1 cup rinsed quinoa** and a pinch of salt. Cover, reduce to low, and simmer **15 minutes**. Remove from heat and rest **5 minutes**, then fluff with a fork.

  Step 4: Sauté the veggie base

  Heat **1 tbsp olive oil** in a large skillet over medium-high heat. Add onion, carrot, and celery. Cook **6–8 minutes**, stirring, until softened and starting to get a little golden at the edges. Add garlic and cook **30 seconds** until fragrant.

  Step 5: Brown the turkey

  Add ground turkey, **1 tsp salt**, and **1/2 tsp pepper.** Cook **5–6 minutes**, breaking it up, until no longer pink and lightly browned (a bit of browning = better flavor).

  Step 6: Build the tomato sauce

  Stir in tomato paste and cook **1 minute** to caramelize slightly. Add diced tomatoes, oregano, cumin, smoked paprika, and red pepper flakes (if using). Simmer **3–4 minutes** until saucy and cohesive.

  Step 7: Mix the filling

  Turn off heat. Stir in the cooked quinoa. Taste and adjust salt/pepper. The mixture should be moist but not soupy; if it looks dry, add a splash of water or broth.

  Step 8: Stuff peppers

  Remove peppers from oven and discard any water that collected inside them. Spoon filling in firmly (pack it in) and mound slightly on top. If using cheese, sprinkle **2 tbsp per pepper** over the top.

  Step 9: Bake

  Cover the dish with foil and bake **15 minutes**. Uncover and bake **10–15 minutes more**, until peppers are tender (a knife slides in easily) and the tops are lightly browned and bubbling.

  Step 10: Rest & serve

  Rest **5 minutes** (this helps them hold together). Finish with parsley/cilantro if using. Serve 1 pepper per person as a satisfying main.

Tips

• **Make it even leaner:** Use **99% lean** turkey and skip cheese; you’ll still get plenty of flavor from spices and the tomato base.
• **Extra veggies, same comfort:** Finely chop spinach or zucchini and stir into the filling during the last minute of simmering (they’ll cook in the oven).
• **No quinoa?** Swap with **brown rice** (cooked) using the same volume as cooked quinoa.
• **Make-ahead:** Assemble stuffed peppers up to **24 hours ahead**, cover, refrigerate, then bake (add **5–10 minutes** if baking from cold).
• **Storage:** Refrigerate leftovers **up to 4 days**. Reheat covered in the oven at **350°F for ~15–20 minutes** or microwave until hot.
• **What to serve with it:** A big green salad or simple roasted vegetables keeps the meal balanced and boosts fiber and micronutrients.
