Gluten-Free Turkey Meatballs with Peppers

These gluten-free turkey meatballs are perfect. The meatballs can stand on their own, but we added peppers, onions, and cheese to make the dish feel complete. There are no breadcrumbs in the meatballs, so they're totally gluten free (and low carb!), but they're still super moist and flavorful.

Why We Love These Meatballs

I follow a gluten-free diet most of the time, so I don't eat a ton of meatballs when we go out. Meatballs usually contain breadcrumbs, which soak up juices from the meat and keep the meatballs moist. I left breadcrumbs out of these meatballs, and instead opted for chopped mushrooms, which add moisture as they cook, preventing the meatballs from drying out. You're left with super moist gluten-free turkey meatballs.

Turkey is a little lighter than traditional beef or pork, but you can't tell in this recipe. The peppers and onions pair perfectly with the marinara sauce and make this recipe feel more like a full meal. Oh, and the cheese. There's so much gooey cheese.

Key Ingredients and Substitutions

Ground Turkey: We used 85% lean for some extra moisture.

Mushrooms: We used baby bellas but any mushroom will work.

Parmesan cheese: It's so much better if you buy fresh parmesan (on the block), and grate it yourself, but pre-grated is fine if you're in a rush (we frequently use pre-grated to save time).

Bell peppers: I used one orange and one yellow, but you can use whatever color you like. Green would work too—I just don't like cooked green peppers that much.

Fresh mozzarella cheese: Fresh mozzarella is so much better than shredded, but you can substitute shredded if you prefer.

Marinara sauce: We love Victoria Marinara Sauce or Rao's. We get both at Costco for a great price, but most grocery stores carry them too.

Step-by-Step Instructions

Step 1: Preheat the oven to 400°F, and line a sheet pan with parchment paper (or spray it with nonstick spray).

Step 2: In a large bowl, combine ground turkey, mushrooms, onion, egg, garlic, basil, parsley, parmesan, Worcestershire sauce, Italian seasoning, salt, black pepper, and crushed red pepper. I find that it's easiest to mix it up with my hands—if that's not your speed, use a spoon.

Step 3: Once everything is combined, form the mixture into the meatballs. We made 16, but that will vary based on how big your make yours—ours were about an inch and a half in diameter.

Step 4: Bake for 20 minutes. After 20 minutes, flip the meatballs and cook for another 20 minutes or until the internal temperature reaches 165 degrees. The cook time will vary based on the size of your meatballs, so keep an eye on them and check the temperature frequently.

Step 5: When the meatballs have about 15 minutes left, add olive oil and onions to a cast-iron pan (or oven-safe pan) and cook for two minutes over medium-low heat, stirring constantly to prevent them from burning.

Step 6: Add bell peppers and cook for an additional five minutes. Then add the garlic and cook for a minute. Add the marinara sauce and crushed red pepper and turn the heat to low.

Step 7: Once the meatballs are done, put them into the pan with the peppers and sauce and cover with mozzarella. Then broil on high for about 5 minutes, or until the cheese is melted (check on them frequently—it happens fast!). Enjoy!

Serving Ideas

Enjoy them by themselves: I eat a gluten-free diet 90% of the time, so I actually prefer eating these meatballs and peppers by themselves. The peppers make this dish feel like a complete meal, and it's super satisfying to me on its own.

Make a meatball sub: These meatballs are perfect for throwing onto a loaf of crusty french bread or a baguette because they're already covered in sauce and cheese. The peppers make it complete. Toast the bread first!

Over pasta: These meatballs and peppers would also be great thrown over spaghetti (like traditional spaghetti and meatballs but with peppers and cheese).
