Break the lasagna noodles into bite-size pieces. (Helping with this may be fun for the kids!)
In a large skillet over medium-high heat, combine the marinara sauce and water and bring to a simmer.
Add the noodles to the skillet and stir to coat. Cover, turn the heat to medium-low, and cook, stirring once or twice, for 15 to 20 minutes, or until the noodles are just soft. (They may stick a little in the middle of the pan so be sure to stir them. Add a little water if needed if the liquid is absorbed before the noodles are completely soft.)
Top with dollops of the ricotta and sprinkle with the mozzarella and Parmesan. Turn off the heat, cover, and let sit for 5 minutes to melt the cheese. Or place under a broiler on high heat for 3 to 5 minutes to melt the cheese and brown it slightly.
Top the lasagna with fresh basil, if desired, before serving.
Notes
Store leftovers in an airtight container in the refrigerator for up to 5 days. Reheat to warm through and serve.
Use a marinara sauce that you love—it's the primary flavoring in this recipe. (You can use meat sauce if desired, too.)
At the end of Step 3, you can also stir in 1 cup cooked broccoli florets, cauliflower, or carrot rounds.
You can make this with meat, if you like. Before starting Step 1, in a large skillet over medium-high heat, brown 1 pound of ground beef or ground sausage. Drain off any excess fat and continue as directed.
If your gluten-free noodles instruct you to rinse them after cooking, prepare them as directed. Then, warm the marinara in the pan, omitting the additional water, and add the cooked g-f noodles. Proceed with the recipe.
