This cozy little bake is my low-carb spin on the cheesy casserole my Aunt Helen always brought to family gatherings. It’s only three ingredients, but somehow it comes out of the oven bubbling, gooey, and so comforting that it feels like you ordered something indulgent from your favorite takeout spot. It’s perfect for busy nights when you want real, homey food without a lot of fuss, and it’s easy enough that older kids can help layer everything together.
Serve these low carb roasted pepper mozzarella bakes hot from the oven with a simple green salad or steamed broccoli to balance all that melty cheese. They’re wonderful alongside grilled chicken or sausage if you want more protein, or you can spoon them over zucchini noodles or cauliflower rice to make a heartier, still low-carb meal. For family movie night, I like to set the casserole dish in the middle of the table with a basket of low-carb crackers or bell pepper strips so everyone can scoop their own cheesy portion.
Low Carb 3-Ingredient Roasted Pepper Mozzarella BakesServings: 4
Ingredients
2 cups jarred roasted red bell peppers, drained and sliced into strips
2 cups shredded low-moisture mozzarella cheese
1/2 cup grated Parmesan cheese
Directions
Preheat your oven to 400°F (200°C). Lightly grease a medium ceramic casserole dish so the cheese doesn’t stick too much.
Pat the roasted red pepper strips dry with paper towels to remove extra moisture and oil. This helps the casserole bake up bubbly and gooey instead of watery.
Spread half of the roasted pepper strips in an even layer over the bottom of the casserole dish, letting some overlap so there are no big gaps.
Sprinkle half of the shredded mozzarella evenly over the peppers, then sprinkle half of the grated Parmesan on top of the mozzarella.
Repeat the layers with the remaining roasted pepper strips, then the rest of the mozzarella, and finally the remaining Parmesan, making sure the top is well covered so it browns nicely.
Place the casserole dish on the middle rack of the preheated oven and bake for 18–22 minutes, or until the cheese is fully melted, bubbling around the edges, and lightly golden on top.
If you like a deeper golden crust, switch the oven to broil for 1–3 minutes, watching closely so the cheese doesn’t burn. The top should be browned in spots with a little glisten of oil.
Remove the casserole from the oven and let it rest for 5–10 minutes. This short rest helps the cheese settle so it’s still gooey but easier to scoop.
Serve warm, scooping out portions with a large spoon. Enjoy as a low-carb main dish or a cheesy side, just like Aunt Helen used to bring to family gatherings.
Variations & Tips
For a little extra flavor without adding more ingredients, choose roasted red peppers packed in olive oil with herbs, then drain well before using. If you have picky eaters, you can chop the roasted peppers into small pieces so they blend more into the cheese and are less noticeable in big strips. To add protein while keeping things simple, serve this bake with grilled chicken, Italian sausage, or leftover rotisserie chicken on the side rather than baking it in. If you need to watch sodium, look for low-sodium roasted peppers and use a light hand with any extra salt at the table, since Parmesan is naturally salty. Food safety tips: Always keep the cheese refrigerated until you’re ready to assemble the dish, and don’t leave the finished casserole at room temperature for more than 2 hours. If you’re using roasted peppers from a jar that’s been open for a while, check the date and give them a quick smell—if anything seems off, throw them out. Store leftovers in a covered container in the refrigerator and reheat thoroughly in the oven or microwave until steaming hot before serving.
