Step-by-Step Instructions
Step 1: Prep and Pre-Bake the Peppers
Preheat your oven to 400°F (200°C). Wash the poblano peppers and slice them in half lengthwise. Remove the seeds and membranes. Drizzle the halves with olive oil and a pinch of salt and pepper. Place them cut-side up on a parchment-lined baking sheet and bake for 10 minutes to soften them.

Step 2: Brown the Meat
While the peppers are in the oven, heat a large skillet over medium-high heat. Add the ground beef and cook until fully browned (about 5-7 minutes). Drain any excess fat from the pan to keep the filling from becoming greasy.
Step 3: Sauté the Aromatics
To the skillet with the beef, add the diced red onion, red bell pepper, and minced garlic. Stir in the chili powder, cumin, paprika, salt, and pepper. Sauté for about 2–3 minutes until the vegetables are just tender and the spices are fragrant.

Step 4: Stuff and Final Bake
Spoon the beef and vegetable mixture generously into the pre-baked poblano halves. Top each pepper with a generous sprinkle of shredded cheddar cheese. Return the pan to the oven and bake for another 10 minutes, or until the cheese is bubbly and golden.

This recipe is a canvas for your favorite flavors. Try these twists:

- Vegetarian: Replace the ground beef with a plant-based crumble or a mix of black beans and quinoa.
Frequently Asked Questions
Are poblano peppers very spicy?
Poblano peppers have a mild-to-medium heat. They are generally spicier than bell peppers but significantly milder than jalapeños. If you want zero heat, use standard bell peppers instead.
How should I store leftovers?
Store any leftover peppers in an airtight container in the refrigerator for up to 5 days.
Can I freeze these?
Yes, you can freeze them for up to 3 months. However, the texture of the pepper will become softer upon thawing. To reheat from frozen, thaw overnight in the fridge and bake at 375°F until warmed through.
