These baked stuffed peppers with ground turkey and lentils have 38 g of protein per serving and take 77 minutes from start to table. The protein comes from ground turkey, green lentils and cheddar, not powder, so it tastes like a regular stuffed pepper.
One serving is a whole pepper (two halves) and weighs about 450 g. That’s a full dinner with no rice on the side. Lentils take the place of rice and supply about 6 g of the protein per serving.
The one thing that goes wrong is a watery dish. Lentils hold a lot of water, so drain them well and simmer the filling until a spoon leaves a trail, or the peppers end up sitting in a puddle.
Most of the 77 minutes is hands-off. The lentils simmer while the turkey browns, then the oven does the rest.
Why You’ll Love This Recipe
- 38 g protein per pepper from turkey, lentils and cheddar
- No rice needed, lentils hold the filling together
- One skillet, one saucepan and one baking dish to wash
- Reheats in the oven and keeps for 4 days
Ingredient Notes
- ground turkey, 93% lean: This is the main protein source at about 93 g across the pan. Ground chicken works the same way, but 99% lean turkey bakes up dry.
- green or brown lentils: Dry lentils add about 25 g protein across the pan and hold their shape when simmered for 18 to 20 minutes. Red lentils fall apart, so skip them here.
- bell peppers: Red, yellow and orange peppers are sweeter than green. Pick ones with flat bottoms so the halves sit level in the dish.
- tomato sauce: Plain canned sauce is fine. Check the sodium on the label, since this recipe already gets salt from the cheddar and seasoning.
- sharp cheddar: Shred it from a block. It contributes about 21 g protein across the pan, so leaving it off drops each serving to about 33 g.
Baked Turkey and Lentil Stuffed Peppers with Cheddar
Ingredients
Method
- Heat the oven to 190 C / 375 F. Put the rinsed lentils and 360 ml water in a 2-quart / 1.9 L saucepan, bring to a boil, then simmer for 18 to 20 minutes until tender but still holding their shape. Drain in a fine-mesh sieve and shake for a full minute so no water is left.
- While the lentils simmer, heat the olive oil in a 30 cm / 12-inch skillet over medium-high heat. Cook the onion for 4 minutes until soft. Add the turkey and break it up, cooking 7 to 8 minutes until no pink remains and it's browned in spots.
- Stir in the garlic, chili powder, cumin, smoked paprika, salt and pepper and cook for 1 minute until fragrant. Add 240 g (1 cup) of the tomato sauce and simmer for 4 to 5 minutes until a spoon leaves a trail through the filling.
- Fold the drained lentils into the turkey mixture and take the skillet off the heat. Spread the remaining tomato sauce (about 185 g) across the bottom of a 23 x 33 cm / 9 x 13 inch baking dish. Set the pepper halves cut-side up on the sauce and mound about 110 g of filling into each half.
- Cover the dish with foil and bake for 25 minutes. Remove the foil, scatter the cheddar over the peppers, and bake 10 more minutes until the cheese is melted and spotted brown, a paring knife slides into the pepper with no push, and the filling reads 165 F / 74 C in the center.
- Rest the peppers in the dish for 5 minutes so the filling firms up. Top with sliced green onions and serve one whole pepper (two halves) per person.
Notes
- Cook the turkey until no pink remains, and confirm the finished filling reads 165 F / 74 C.
- Cut peppers lengthwise through the stem so each half keeps a flat, stable base.
- Shred cheddar from a block, since pre-shredded cheese melts less evenly.
- Spread the sauce thinly under the peppers so the dish doesn't turn into soup.
Tips for Success
- Drain the cooked lentils in a fine-mesh sieve and shake for a full minute, because leftover water turns the filling soupy.
- Cut peppers lengthwise through the stem and trim any bulging bottoms so each half sits level in the dish and holds its filling.
- Check the center of the filling with an instant-read thermometer, and bake until it reads 165 F / 74 C before pulling the dish.
- Buy 93% lean ground turkey, since 99% lean bakes up dry and 85% leaves grease pooled around the peppers.
- Taste the filling before stuffing and add salt if needed, because plain peppers and lentils mute the seasoning after baking.
Variations
- Swap the chili powder, cumin and paprika for 2 tsp Italian seasoning and use shredded mozzarella for an Italian-American version with nearly the same protein.
- Use 6 large poblano peppers instead of bell peppers, halved, and top with pepper jack for a spicier Tex-Mex bake.
- Stir 100 g frozen corn and one diced jalapeno into the filling along with the lentils for sweetness and a little heat.
Storage and Reheating
Baked turkey and lentil stuffed peppers keep for 4 days in the fridge in an airtight container. Let them cool for 30 minutes, then refrigerate within 2 hours of baking.
To reheat, set the peppers in a baking dish, cover with foil and heat at 175 C / 350 F for 20 minutes, until the center reads 165 F / 74 C. The oven keeps the pepper from going watery.
For longer storage, wrap each pepper tightly and freeze for up to 3 months. I keep a few in the chest freezer in the garage. Thaw overnight in the fridge, then reheat covered for 25 minutes.
Serving Suggestions
Baked turkey and lentil stuffed peppers work as a full dinner on their own, since each one already has about 38 g of protein and no rice is needed underneath.
I serve them with a crisp green salad dressed in lime juice and olive oil, or a square of cornbread to mop up the tomato sauce. A spoonful of plain Greek yogurt on top adds about 3 g protein per 2 tablespoons.
Sprinkle sliced green onions over the top and put hot sauce on the table. Give the peppers 5 minutes of rest first so the filling firms up when you cut in.
FAQ
Why are my stuffed peppers with lentils watery at the bottom of the dish?
Watery peppers come from lentils that weren’t drained well or a filling that was too thin going into the oven. Shake the lentils in a sieve for a full minute, then simmer the turkey and sauce until a spoon leaves a trail. Spread only about 185 g of sauce under the peppers, not more.
Can I use canned lentils instead of cooking dry lentils for stuffed peppers?
Yes, use one 425 g (15 oz) can, drained and rinsed well, which gives about 250 g of cooked lentils. Protein lands within 1 g per serving of the dry version. The time saving is small since the lentils simmer while the turkey browns, but you skip one saucepan.
Can I freeze stuffed peppers with ground turkey and lentils?
Yes, they freeze for up to 3 months. Cool them completely, wrap each pepper tightly, then bag them. Thaw overnight in the fridge and reheat covered at 175 C / 350 F for 25 minutes, until the center reads 165 F / 74 C. The pepper skin comes out a little softer after freezing.
What goes well with turkey and lentil stuffed peppers?
A crisp green salad with lime vinaigrette and a square of cornbread are the two sides I use most. The peppers already carry the protein, so sides just add crunch and something to mop up the tomato sauce. A spoonful of plain Greek yogurt on top adds about 3 g protein per 2 tablespoons.
How do I make these stuffed peppers dairy free and how much protein do I lose?
Leave off the cheddar and bake the peppers uncovered for the last 10 minutes as written. That drops about 5 g protein per serving, leaving roughly 33 g. Dairy-free shreds melt fine but usually add almost no protein, so don’t count on them to make up the difference.
What is the difference between these stuffed peppers and classic stuffed peppers with rice?
Classic American stuffed peppers use cooked rice in the filling, often with ground beef. Here lentils replace the rice, which adds about 6 g protein per serving and gives a firmer, less sticky filling. The seasoning leans Tex-Mex with chili powder and cumin, while the sauce and cheddar keep it close to the Italian-American version.
