Why You Must Make:

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 ventured to Des Moines to an Italian market. But with 4 young girls, that wasn’t going to happen!

  • If you haven’t made lasagna with ricotta cheese, this is the perfect recipe to try.
  • Adding Italian sausage gives loads of flavor to the sauce.
  • There’s lots of gooey Mozzarella cheese, and who doesn’t love a cheesy pasta dish????

Ingredient Notes

There are so many different versions of lasagna, but for this ricotta lasagna, add these ingredients to your shopping list:

  • Italian Sausage – It can be mild or spicy depending on your preference, saute it first for the best flavor. Browning the sausage first starts the Maillard reaction between amino acids and sugar which adds umami or the savory sense of taste.
  • Whole milk ricotta – The additional fat with the whole milk version makes a creamier result.
  • Lasagna noodles – If you want to use the no-boil lasagna noodles, make sure your sauce isn’t too thick as the noodles need liquid for them to soften. If you use regular dried lasagna noodles, cook as directed on the box in well-salted water. The cooking water should taste like seawater. Noodles with salt added after cooking will never be as tasty as those cooked in salted water.

Homemade Ricotta

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.

Expert Tips

  • Adding cooked Italian sausage slices or bulk Italian sausage to the tomato sauce 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.
  • PRO-Tip: 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.

Recipe Tips

  • 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, ¼ cup grated Parmesan, 1 teaspoon dried basil, ½ teaspoon salt and ¼ teaspoon freshly ground black pepper. Layer this mixture in place of the plain ricotta.

Frequently Asked Questions

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.

Can You Make Ricotta Cheese at Home?

Yes, if it’s not available at your grocery store, you can make it with four simple ingredients. Here’s my sister’s recipe:
1. Squeeze 2-3 fresh lemons to make 7 Tablespoons. 
2. Place the lemon juice, ½ gallon whole milk, 1 cup heavy cream, and ¼ teaspoon of salt into a pan over medium-low heat.
3. Allow mixture to heat for 45 to 50 minutes until temperature reaches 165 to 170 degrees.
4. Stir the mixture once or twice to avoid sticking. But don’t stir too much otherwise the ricotta curds will be too small.
5. Increase heat slightly for another 7 to 8 minutes or until it reaches 200 to 205 degrees on the edges and in the middle.
6. Remove ricotta from the heat and allow it to rest for 15 minutes. Line a colander with a double thickness of damp cheesecloth. Pour the curds into the colander.
7. Allow the ricotta to drain for 20 minutes.
This makes 16 ounces of yummy light slightly lemony ricotta. Perfect for pasta, salads, or even cheesecake.
