- 15/16 lbs part-skim ricotta cheese
- 1/4 cup grated Parmesan cheese
- Kosher salt and pepper
- 3/4 lbs lean ground beef
- 1/2 tsp dried oregano
- 1 5/8 lbs marinara sauce

Prepare
- Shred 1/2 lbs part-skim mozzarella cheese
- 2 cup baby spinach, roughly chopped
- 2 clove garlic, finely chopped
Let's Cook
-
Step 1.
In a medium bowl, combine the ricotta, 1 cup of the shredded mozzarella, the grated Parmesan, and ¼ teaspoon each salt and pepper. Fold in the roughly chopped baby spinach until evenly distributed. Set aside.
-
Step 2.
In a 5- to 6-quart slow cooker, combine the lean ground beef, finely chopped garlic, dried oregano, ½ teaspoon salt, and ¼ teaspoon pepper. Transfer half of this meat mixture to a small bowl and set aside. Add ½ cup of the marinara sauce to the slow cooker and mix into the remaining meat. Spread the meat mixture evenly on the bottom of the slow cooker.
-
Step 3.
Top the meat layer with a layer of dry lasagna noodles, breaking them to fit as needed. Spread one-third of the remaining marinara sauce (about ¾ cup) over the noodles. Dollop one-third of the ricotta mixture (about 1 cup) over the sauce, then sprinkle with half of the reserved meat mixture. Repeat the layering: another layer of noodles, another one-third of sauce, another one-third of ricotta mixture, and the remaining meat mixture.
-
Step 4.
Top with a final layer of noodles, the remaining sauce, and the remaining ricotta mixture. Sprinkle the remaining 1 cup of shredded mozzarella evenly over the top. Cover the slow cooker and cook on low for 4 hours or on high for 2 hours, until the noodles are tender and the lasagna is bubbling. Let rest for 10 minutes before serving.
