Why You Must Make

  • Did you know you don’t have to cook your lasagna noodles before baking? And how about your sauce? Have you tried an uncooked version? This recipe adapted from Red Gold, a purveyor of prime tomatoes, had a couple of nifty shortcuts that made creating this layered pasta a wee bit simpler. I took their Easy Classic Lasagna and with a couple of tweaks transformed it into this Easy Sausage and Mushroom Lasagna.
  • It’s easily adaptable. Don’t like mushrooms? Leave them out. Not a fan of Italian sausage? Use ground beef instead.
  • Lasagna is hearty, delicious comfort food. Try this easy homemade lasagna when you’re in the mood for some Italian fare.

Ingredient Notes:

  • Pantry Staples – Olive Oil, Water, Salt
  • Medium Onion – I use a white onion; peel and chop.
  • Sliced Mushrooms – I use button mushrooms. Trim off the very end of the stems, then slice if you purchased whole mushrooms.
  • Mild Italian Sausage Links Sliced or Ground – Note that it’s easier to slice sausage links when frozen. Brown before adding to the lasagna to add umami (savory sense of taste). May use ground beef as an alternative.
  • Canned Crushed Tomatoes – Use the puree in the can, too.
  • Canned Diced Tomatoes With Basil, Garlic & Oregano (use 2 cans). If unavailable, use plain diced tomatoes and add some dried basil, dried oregano, and garlic powder to taste.
  • Box of Lasagna Noodles – Traditional, uncooked, 16-ounces.
  • Low-fat Ricotta Cheese -Full-fat works, too.
  • Shredded Mozzarella Cheese – Full-fat tastes best.
  • Grated Parmesan Cheese – Make sure it’s real Parmesano Reggiano, not the green can.

Recipe Tips

I’ve made tons of lasagnas..or “rizzoni” as my daughter, Katie, dubbed it as a toddler. But I hate how many messy dishes there are to wash when it’s all said and done.

  • I started soaking my lasagna noodles in hot water instead of boiling them when I learned of that shortcut, and when no-boil pasta came out, I tried that as well.
  • PRO-Tip: But the easiest time-saving trick is to make a more watery sauce and just use the pasta straight out of the box. As the lasagna cooks, the noodles absorb the excess water and are cooked to perfection.
  • And doubly nice is that this pasta sauce is uncooked; there are fewer pots and pans to wash after the prep is finished.
  • PRO-Tip: Brown your meat, whether you use ground beef or sausage. This increases the flavor due to the Maillard reaction.
  • Let your lasagna rest for 20-30 minutes after it comes out of the oven before slicing. This allows the layers to firm up a bit.
  • PRO-Tip: If you like a spinach lasagna, you can add some defrosted, frozen chopped spinach that has been squeezed dry, to the ricotta cheese.
  • My mom made lasagna using cottage cheese since ricotta was hard to come by in small towns back in the 1970s. It’s a viable alternative if you can’t procure ricotta, either.
  • Red Gold also has recipes for Chicken Parmesan Lasagna, Fresh Harvest Lasagna, and Eggplant Florentine Lasagna on their website. They’re all a twist on the same Classic Lasagna from which this recipe was based.
