These stuffed poblano peppers use 99% lean ground turkey, cauliflower rice, and canned vegetables to make a filling that comes in at 258 calories per serving. Poblanos are milder than jalapeños but have more flavor than bell peppers, which makes them a better vessel for a well-seasoned turkey filling. The whole thing comes together in 35 minutes using one pot and one baking sheet.
What makes this version work
Two things matter here. First, pre-baking the pepper halves for 5–10 minutes before filling them means the shells are already partially cooked when the filling goes in — you avoid the common problem of underdone, bitter-tasting pepper walls around a fully cooked filling. Second, cooking the cauliflower rice directly in the filling rather than separately lets it absorb the liquid from the tomatoes, salsa, and broth instead of turning watery. It binds the filling just enough so it doesn’t fall out when you eat the pepper, and you don’t need an extra pan to cook the cauliflower rice first.
Mistakes to avoid
- Skipping the drain on the canned tomatoes: If you add them undrained, the filling becomes soupy and won’t hold in the pepper halves. Press them briefly in a sieve before adding.
- Overfilling the peppers: Piling the filling too high means it slides off during the final bake. Fill to just level with the rim of the pepper — the filling firms up slightly in the oven.
- Pulling the turkey off heat before it’s done: Ground turkey must reach 165°F (74°C) internally. At 99% lean, it can look pale and cooked before it actually is. Use a thermometer or cut into the thickest piece to confirm no pink remains.
- Adding the cheese too early: Low-fat mozzarella dries out fast. The recipe’s 2–3 minute window at the end is correct — skip the garnish of extra cheese on the side, not worth the extra dish.
- Using small or thin-walled poblanos: Thin-walled peppers collapse during pre-baking and can’t hold the filling. Pick large, firm poblanos with thick walls at the store.
Make-ahead notes
The filling can be made up to 2 days ahead and stored in an airtight container in the fridge — keep it separate from the peppers so the shells don’t go soggy. Assemble and bake when you’re ready to eat. Fully cooked stuffed peppers keep in the fridge for 3 days; reheat covered in a 350°F (175°C) oven for 12–15 minutes, or microwave on medium power in 90-second bursts until the center hits 165°F (74°C). For freezing, freeze the filling only — the pre-baked pepper halves turn mushy after thawing. Freeze filling flat in a zip bag for up to 2 months, thaw overnight in the fridge, then pre-bake fresh peppers and assemble as normal.

½ cup cilantro - fresh ; roughly chopped, about 8g
1 oz mozzarella cheese - low-fat, about 28g- 2 tablespoons salsa verde - green salsa
3 tablespoons vegetable stock (vegetable broth or vegetable bouillon) - 45ml (broth or bouillon)- 1 can non-stick cooking spray - such as olive oil or avocado oil spray
¼ teaspoon salt - adjust to taste
¼ teaspoon ground black pepper - adjust to taste

Instructions
- Preheat your oven to 400°F / 200°C (205°C fan-forced). Wash your poblano peppers and cut them in half to open them up. I like to place them with the widest stem end flat down on my cutting board and then cut straight down starting from the narrow end. Remove seeds and stem.4 large poblano peppers
- On a baking sheet lined with aluminium foil, sprayed lightly with non-stick cooking spray, place all your pepper halves open side facing up on your sheet. To ensure they don’t overlap, you may need two sheets. Place in the oven. Bake for 5–10 minutes until slightly softened but still holding their shape — check at the 5-minute mark to avoid over-softening. Set aside.4 large poblano peppers, 1 can non-stick cooking spray
- Sauté the onions in a medium pot lightly coated with non-stick cooking spray over medium-high heat for 2–3 minutes until softened and translucent.2 ounces yellow onion, 1 can non-stick cooking spray
- Turn the heat down to medium, add the ground turkey and chilli powder, and cook for 4–5 minutes, breaking the meat into small crumbles with a spoon, until no pink remains and the internal temperature reaches 165°F / 74°C. Add the broth and stir to deglaze the pot.5 ounces ground turkey, 1/2 teaspoon chili powder (chilli powder in British English), 3 tablespoons vegetable stock (vegetable broth or vegetable bouillon)
- Add the frozen riced cauliflower, drained diced tomatoes, lime juice, chopped cilantro, tomato sauce, corn kernels, and salsa verde. Add the salt, black pepper, garlic powder, paprika, taco seasoning, and cumin. Stir everything together over medium heat for 3–4 minutes until the cauliflower rice is heated through and has absorbed most of the liquid.6 ounces frozen riced cauliflower, 1 can diced tomatoes, 1 tablespoon lime juice, 1/2 cup cilantro, 4 ounces tomato sauce, 3 oz corn kernels, 2 tablespoons salsa verde, 1/4 teaspoon salt, 1/4 teaspoon ground black pepper, 1/4 teaspoon garlic powder, 1/4 teaspoon paprika, 1/2 teaspoon taco seasoning, 1/4 teaspoon cumin
- Next is the fun part. Take a spoon, start stuffing your poblano peppers. Some of the “deeper” peppers will need more filling than the “shallow” ones.4 large poblano peppers
- Return the stuffed peppers to the oven at 400°F / 200°C and bake for 8–10 minutes until the filling is bubbling at the edges. Remove, top each pepper half with mozzarella cheese, and return to the oven for 2–3 minutes until the cheese is melted and lightly golden. Plate and enjoy!1 oz mozzarella cheese

Frequently asked questions
Can I use ground beef or chicken instead of turkey?
Yes, both work. Ground chicken behaves almost identically to turkey and must also reach 165°F (74°C) internally. Ground beef (80/20) will add more fat to the filling, which changes the texture slightly — drain any excess fat from the pan before adding the cauliflower rice and vegetables.
How spicy are poblano peppers?
Poblanos are mild — most rate between 1,000 and 2,000 Scoville units, which is significantly less heat than a jalapeño. Occasionally you’ll get one with a bit more kick, but it’s rare; this recipe is generally suitable for people who don’t like spicy food.
Can I use regular rice instead of cauliflower rice?
You can, but cook the rice fully before adding it to the filling — raw rice won’t cook through during the short oven time. Cooked regular rice will also absorb more liquid, so reduce the vegetable stock by half to keep the filling from getting wet.
My peppers keep tipping over on the baking sheet. How do I keep them stable?
Trim a very thin slice off the rounded underside of each pepper half to create a flat base before pre-baking. Alternatively, scrunch small pieces of foil into supports and nestle each pepper half against them on the sheet.
