Tips for Making the Best Lasagna Stuffed Peppers
Below, find a handful of tips and tricks to help you make the best lasagna stuffed peppers possible.
- Make the filling a day ahead of time for extra flavor. If you have the time, whip up your filling the day before and let it marinate in the fridge overnight. This will pack an extra punch of flavor and make assembling the peppers the next day that much easier!
- Use cottage cheese instead of ricotta for healthier peppers. Traditionally, lasagna is made with ricotta cheese. This recipe calls for cottage cheese to keep it light. Don’t worry, the peppers will still be just as creamy…
- Use lean ground turkey. Lean ground meats produce much less oil when browned. This will prevent your filling from becoming too watery. If you use ground meat with higher fat content, make sure to strain out as much liquid fat as possible before adding your marinara sauce.
- Don’t overstuff the peppers. When spooning in the meat mixture, leave some space at the top to prevent the filling from boiling over the sides of the pepper. A couple of centimeters will do the trick.
- Stack the peppers side by side. To keep the peppers upright when baking, stack them side by side. There’s nothing worse than a pepper toppling over in the oven!
Hot Tip: Gauge the size of the baking dish you will use by stacking empty, raw peppers in the dish before stuffing. Since peppers come in all shapes and sizes, you may need a bigger or smaller dish.
Serving Lasagna Stuffed Peppers
You can serve your lasagna peppers as a quick weeknight meal or packed in your lunch. Although filling enough to be eaten all on their own, they pair wonderfully with a variety of different side dishes. If you’re being mindful of carbs, serve them alongside a homemade caesar salad for a well-rounded meal. If you’re not watching your carbs closely, bake a baguette to sop up all that wonderful sauce. They also go great with some smashed potatoes.
Storing Lasagna Stuffed Peppers
- Refrigerator: Store stuffed bell peppers in an airtight container in the refrigerator. They should last for an entire week.
- Freezer: Freeze stuffed bell peppers by allowing them to cool completely. Wrap each individual bell pepper tightly in plastic wrap. Pop them into the freezer-safe bag and enjoy them for up to three months.
FAQ
Do you have to cook the ground meat before stuffing the peppers?
You should always cook the ground meat before stuffing your peppers. While raw meat will likely cook in the oven, it’s hard for it to cook evenly within the sauce. Always stay on the safe side by browning it first.
Why are my stuffed peppers watery?
Your stuffed peppers are likely watery if you used fattier ground meat. To prevent watery peppers, always use lean ground meat and drain your pan of any excess liquid before mixing it into your sauce.
How long does it take for peppers to get soft?
It takes peppers about 30 minutes at 350°F to get soft. If your peppers are still too tough after 30 minutes, bake the peppers in 5-minute increments until desired texture is reached.
How long does it take to parboil bell peppers?
It takes only 2-3 minutes to parboil peppers. Although this step is not required for this recipe, feel free to parboil the peppers before stuffing them if you like them extra soft.

Do you have to put cottage cheese in it? Could you only use Mozzarella cheese?
Hi Sherry - Thanks for reaching out. Cottage cheese adds a nice moisture content and creaminess that mozzarella wouldn't be a good substitute for. I would recommend using ricotta if you don't like cottage cheese. Hope this helps and Happy New Year!
