How To Make This Scrumptious Lasagna

There are a few tips on how to make this lasagna easy. The best thing to do is buy lasagna noodles that don’t need to be boiled and bottled pasta sauce. This will save you cooking and preparation time for the slow cooker lasagna.

Spray your slow cooker with oil to prevent sticking, and pour a cup of the pasta sauce in the slow cooker. Cover the sauce with the lasagna noodles, and start the layering process. The process will go as follows: sauce, noodles, ricotta cheese, a bit of sauce, and repeat.

You should repeat the cycle around 3 times, depending on how much sauce and cheese you like in your lasagna. The top layer should be sauce, and optionally some parmesan cheese.

Cover the slow cooker and cook it low and slow for 4 to 6 hours, or on high heat for 2 to 3 hours.

After it cooks, let it cool down for about 30 minutes so that it can solidify and not become lasagna soup! Slice up and serve them warm, rich lasagna.
