Spicy Stuffed Poblano Peppers
Smoky poblano peppers packed with a chipotle-spiced black bean and quinoa filling, loaded with melted Mexican cheese and finished with cool Greek yogurt.
Poblanos are one of the best peppers for stuffing because they've got this mild, smoky heat that builds without burning your face off. Most stuffed pepper recipes use bell peppers, which are fine, but boring. Poblanos bring actual flavor to the table. And when you add a hit of chipotle in adobo to the filling, you've got layers of heat that keep things interesting. Fun fact about all that capsaicin: it's thermogenic, meaning your body burns a few extra calories just processing the heat. Not a huge deal, but I'll take free calorie burn with my dinner.
The filling here is where the protein math works out. Quinoa is already one of the few plant-based complete proteins, and when you mix it with black beans, you're stacking amino acids in a way that's genuinely competitive with meat. Throw in a cup of shredded Mexican cheese blend that melts into everything, and each serving hits 28g protein. For a meal that's mostly vegetables and grains, that's serious.
These are also a meal prep monster. I'll assemble a whole tray on Sunday, stuff the peppers, wrap the tray, and just pop it in the oven when I need dinner during the week. They actually get better after sitting overnight because the filling soaks up all the chipotle flavor. Twenty-five minutes in the oven from the fridge, and you've got a hot meal with legit macros.
The Protein Upgrade
Traditional stuffed peppers often rely on rice and vegetables with a light sprinkle of cheese, delivering around 12-15g protein. We swap rice for quinoa (a complete protein), add two full cans of black beans, and use a generous cup of Mexican cheese blend, pushing each serving to 28g protein.
Spicy Stuffed Poblano Peppers
Ingredients
- 4 large poblano peppers (halved lengthwise and seeded)
- 2 cans (15oz) black beans (drained and rinsed) 11g protein
- 1 cup quinoa (cooked (about 0.5 cup dry)) 2g protein
- 1 ½ cups Mexican cheese blend (shredded) 9g protein
- ¾ cup corn kernels (fresh or frozen)
- 2 tbsp chipotle peppers in adobo (minced)
- 1 tsp cumin
- 3 cloves garlic (minced)
- 1 medium onion (diced)
- 1 tbsp olive oil
- ½ tsp salt
- ¼ tsp black pepper
- ½ cup Greek yogurt (for topping) 2g protein
- ¼ cup fresh cilantro (chopped, for garnish)
Instructions
- Preheat oven to 375°F. Line a baking sheet with parchment paper.
- Halve the poblano peppers lengthwise and remove the seeds and membranes. Place cut-side up on the baking sheet and drizzle lightly with olive oil.
- Heat olive oil in a large skillet over medium heat. Sauté the diced onion until softened, about 4-5 minutes. Add the garlic and cumin, cooking for 1 minute until fragrant.
- Add the drained black beans, cooked quinoa, corn kernels, and minced chipotle peppers to the skillet. Stir well and cook for 3-4 minutes until heated through. Season with salt and pepper.
- Remove from heat and stir in half of the shredded cheese, letting it melt into the filling.
- Spoon the filling generously into each poblano half, mounding it up. Top each pepper with the remaining cheese.
- Bake for 25-30 minutes until the peppers are tender and the cheese is bubbly and golden.
- Let cool for 5 minutes, then top each pepper with a dollop of Greek yogurt and a sprinkle of fresh cilantro. Serve two halves per person.
Boost Your Protein
- Mix 0.5 cup of cottage cheese into the filling before stuffing for an extra 7g protein per serving.
- Use a three-cheese blend (add cotija) for a more complex flavor and a slight protein bump.
- Serve alongside a simple black bean soup for a complete high-protein Mexican meal.
Ingredient Substitutions
- No poblano peppers? Use bell peppers or Anaheim peppers.
- No quinoa? Use cooked rice or couscous.
- No chipotle peppers in adobo? Use smoked paprika with a dash of cayenne.
- Swap Mexican cheese blend for Monterey Jack or crumbled queso fresco.
