How to Make Roasted Red Pepper and Spinach Lasagna
-
Preheat the oven to 375°F (190°C). Prepare your 9×13-inch baking dish by lightly greasing it with olive oil or cooking spray to prevent sticking.
-
Combine ingredients in a large bowl. Mix the ricotta cheese, drained spinach, chopped roasted red peppers, onion, minced garlic, Italian seasoning, salt, and pepper until well incorporated. This will be your flavorful filling!
-
Spread a thin layer of pasta sauce at the bottom of your baking dish. This creates a tasty base that keeps your lasagna moist as it bakes.
-
Layer the cooked lasagna noodles over the sauce. Take a moment to evenly spread the ricotta mixture on top, ensuring each noodle is well covered. Then, sprinkle a generous amount of mozzarella and Parmesan cheese over the filling.
-
Repeat the layers until you’ve used all ingredients. Finish with a top layer of pasta sauce, followed by the remaining mozzarella and Parmesan cheese to create that delectable crust.
-
Cover the lasagna with foil and bake for 25–30 minutes. After this time, remove the foil and let it bake for an additional 10–15 minutes. Look for that golden, bubbly cheese on top.

Chef's Helpful Tips
- For the Roasted Red Pepper and Spinach Lasagna, ensure you cook the lasagna noodles al dente, as they will continue to soften while baking.
- A common mistake is not squeezing out excess water from the thawed spinach, which can make the filling too watery.
- When layering, make sure to evenly spread the ricotta mixture to prevent dry spots and ensure a rich flavor in every bite.
- Remember to let the lasagna rest for 10–15 minutes after baking, as this helps it set and makes for neater slices when serving.
Roasted Red Pepper and Spinach Lasagna Recipe FAQs
What type of lasagna noodles should I use?
I recommend using either traditional lasagna noodles or the no-boil variety for this recipe. If using traditional noodles, cook them al dente to ensure they hold their shape and texture when baked. For no-boil noodles, simply layer them dry in the lasagna, as they will absorb moisture from the sauce during baking.
How do I know if my spinach is thawed properly?
To ensure your frozen spinach is thawed correctly, let it sit in the fridge overnight or use the microwave for a quicker option. Once thawed, squeeze out as much water as you can—ideally, it should be dry or only slightly moist. Excess water can make your lasagna fillings soggy, so don’t skip this step!
How should I store leftover lasagna?
Store any Roasted Red Pepper and Spinach Lasagna leftovers in an airtight container in the fridge for up to 3 days. Make sure to press down the surface to remove air and cover tightly with plastic wrap or foil to maintain moisture and enhance flavor. It’s a fantastic dish that gets even better after a night in the fridge!
Can I freeze Roasted Red Pepper and Spinach Lasagna?
Absolutely! To freeze the lasagna, I recommend wrapping it tightly in plastic wrap, followed by a layer of aluminum foil to prevent freezer burn. You can freeze it before baking for up to 3 months. When you’re ready to enjoy, thaw it overnight in the fridge and reheat in the oven at 375°F (190°C) covered with foil for about 25–30 minutes until heated through.
What should I do if my lasagna is too watery?
If you find your lasagna is too watery after baking, it might be due to excess moisture in the spinach or other ingredients. To fix this, make sure to thoroughly drain and squeeze out the spinach. Additionally, using less sauce in the layers can also help keep your lasagna from getting too soupy. Aim for a balanced mixture when layering the ingredients.
