Lasagna with Ricotta Cheese

My mom used to make lasagna with cottage cheese. I guess that’s the way it was done in the Midwest way back when. Ricotta cheese was not readily available unless she’d venture to Des Moines to an Italian market. But with 4 young girls, that wasn’t going to happen!

It wasn’t until a dinner party at some dear friends’ house that I first tasted this fabulous lasagna recipe made with ricotta cheese. Since that time, this Italian sausage lasagna is my go-to recipe.

What is Ricotta?

Ricotta translates to recooked in Italian since it was originally made from the whey. Whey is the liquid leftover liquid after milk is used to make something else, like cheese. An acid and some milk is typically added to the whey to help coagulate the proteins and form ricotta. Now, in the US, ricotta is made with whole milk instead of whey, but using the same technique to make the curds which become a fluffy ricotta cheese.

Creating homemade ricotta is really quite easy, but it’s even easier to buy it at the market! Besides lasagna, ricotta can be used in stuffed shells, manicotti, on pizza, as a smear instead of cream cheese, in dips and to dollop on soups.

Adding cooked Italian sausage slices or bulk Italian sausage is a way to incorporate more flavor into every bite. Since my mostly vegetarian daughter does not enjoy meat in her lasagna or spaghetti sauce, adding slices is easier for her to pick around.

Instead of adding raw sausage, cooking it first helps intensify the flavors through the browning process, something known as the Maillard reaction. By way of cooking, the amino acids in the meat and the reducing sugars have a chemical reaction giving the distinct, delicious flavor of browned meat. So make sure to get a little color on the sausage while sauteing for the best outcome.

How to Make Lasagna with Ricotta Cheese

Simmering a flavorful sauce for 2+ hours provides a delicious foundation for your lasagna. Using crushed tomatoes makes for a nice sauce consistency.

The addition of cooked sausage or ground beef adds that umami, or layer of meaty flavor.

Use either shredded or sliced mozzarella for the cheesy component. This time, I used shredded.

My preference is whole milk ricotta. It’s difficult to spread over the sauce, so I disperse spoonfuls of ricotta over the sauce.

Bake with greased or non-stick foil covering the lasagna. At the end of the baking time, remove the foil and broil for a couple of minutes or let the heat of the oven brown the cheese a bit if desired.

PRO-Tip: For a meatless lasagna, or a Lasagna with Spinach, eliminate the sausage. Then mix the ricotta with a defrosted, squeezed dry 9-ounce box of frozen chopped spinach along with an egg, 1/4 cup grated Parmesan, 1 teaspoon dried basil, 1/2 teaspoon salt and 1/4 teaspoon freshly ground black pepper. Layer this mixture in place of the plain ricotta.
