Skillet Lasagna with Sausage and Peppers

From America's Test Kitchen

Lasagna isn’t usually a dish you can throw together at the last minute. Even with no-boil noodles, it takes a good amount of time to get the components just right. Our goal was to transform traditional baked lasagna into a stovetop skillet dish without losing any of its flavor or appeal.

We built a hearty, flavorful meat sauce with onions, garlic, red pepper flakes, and sausage (a more flavorful alternative to plain ground beef). A large can of diced tomatoes along with tomato sauce provided juicy tomato flavor and a nicely chunky texture. We scattered regular curly-edged lasagna noodles, broken into pieces, over the top of the sauce (smaller pieces are easier to eat and serve). We then diluted the sauce with a little water so that the noodles would cook through. After a 20-minute simmer with the lid on, the pasta was tender, the sauce was properly thickened, and it was time for the cheese. Stirring Parmesan into the dish worked well, but we discovered that the sweet creaminess of ricotta was lost unless we placed it in heaping tablespoonfuls on top of the lasagna. Replacing the lid and letting the cheese warm through for several minutes was the final step for this super-easy one-pan dish.
