Prep the peppers: Preheat the oven to 375°F (190°C). Slice the tops off the bell peppers and remove seeds and membranes.
If they don’t stand upright, trim a thin sliver off the bottoms to level them without creating holes. Place in a baking dish.
Par-bake (optional but helpful): For softer peppers, rub the insides with a little olive oil and bake for 10 minutes while you make the filling.
Sauté aromatics: Heat olive oil in a large skillet over medium. Add onion and a pinch of salt.
Cook 3–4 minutes until softened. Add garlic and cook 30 seconds until fragrant.
Brown the beef: Add ground beef. Cook, breaking it up, until no longer pink, 5–7 minutes.
Drain excess fat if needed.
Season the mixture: Stir in smoked paprika, onion powder, garlic powder, salt, and pepper. Cook 1 minute to bloom the spices.
Add “burger” elements: Stir in ketchup, mustard, Worcestershire, chopped pickles, and Greek yogurt (or light cream cheese). Mix until creamy and cohesive.
Taste and adjust salt, pepper, and ketchup/mustard balance as needed.
Add the rice (optional): Fold in cooked brown rice or cauliflower rice for extra volume and texture. Warm through for 1–2 minutes.
Cheese it: Stir in half of the shredded cheddar until just melted. This binds the filling and amps up the cheeseburger vibe.
Stuff the peppers: Spoon the filling into each pepper, pressing gently to pack.
Mound slightly on top. Sprinkle the remaining cheese over each pepper.
Bake: Add a splash of water (about 1/4 cup) to the baking dish, cover with foil, and bake 20 minutes. Remove foil and bake another 8–10 minutes, until the peppers are tender and cheese is bubbly and golden.
Rest and serve: Let cool for 5 minutes so the filling sets.
Add optional toppings like shredded lettuce, tomato slices, or a few extra pickle chips. Serve warm.
