Slow Cooker Mushroom Spinach Lasagna Recipes

Steps:

• Add the butter to a 6-quart Instant Pot® and set to high saute (see Cook's Note). When melted, add the mushrooms and 2 teaspoons salt and cook, stirring occasionally, until golden brown, 8 to 10 minutes. Stir in the flour and nutmeg and cook for 1 minute. Whisk in the milk, bring to a boil and cook until thick and creamy, about 5 minutes. Transfer the bechamel sauce to a medium bowl and set aside. Add 2 cups water to the pot (no need to clean the pot first) and put the rack in the bottom with the handles folded under.
• Meanwhile, mix together the spinach, basil, ricotta, red pepper flakes, garlic, 1 cup Parmesan and 1 teaspoon salt in a medium bowl until completely combined.
• Spread 1/2 cup marinara sauce on the bottom of an 8-inch round cake pan. Break 4 lasagna noodles into large pieces and arrange in an even layer over the sauce. Spread another 1/2 cup marinara sauce evenly over the noodles. Layer a third of the bechamel over the marinara and top with a third of the spinach mixture. Top with another layer of 4 broken noodles. Repeat the process 2 more times, starting with 1/2 cup marinara and ending with broken noodles, for a total of 4 layers of noodles. Top with the remaining marinara and cover tightly with foil, wrapping any excess underneath (if you bunch the foil on the side of the pan it won't fit in the pot).
• Fold an 18-inch piece of foil in half lengthwise, then in half again lengthwise and finally once more in half lengthwise, making a 4 1/2-inch-wide foil sling for the pan. Place the cake pan with the lasagna in the center of the sling and lower into the pot.
• Follow the manufacturer's guide for locking the lid and preparing to cook. Set to pressure cook on high for 25 minutes.
• After the pressure-cook cycle is complete, follow the manufacturer's guide for natural release. After 15 minutes, being careful of any remaining steam, unlock and remove the lid.
• Position a rack in the upper third of the oven and preheat the broiler to high.
• Remove the foil from the lasagna and top with the mozzarella and remaining 1/4 cup Parmesan. Broil until the cheese is melted, bubbling and brown in spots, 1 to 4 minutes. Let sit 10 minutes before serving.

Steps:

• Heat oil in large skillet on medium heat. Add mushrooms; cook and stir 3 min. Add spinach; cook 3 min., stirring occasionally. Stir in tomato sauce, tomatoes and Italian seasoning. Bring to boil; simmer on medium-low heat 3 min. Meanwhile, mix ricotta, 1/4 cup Parmesan and pepper until blended.
• Spread 3/4 cup tomato sauce mixture onto bottom of slow cooker sprayed with cooking spray; top with 3 noodles, breaking as necessary to fit, and 3/4 cup of the remaining tomato sauce mixture. Cover with ricotta mixture, 1 cup shredded cheese, 3/4 cup tomato sauce mixture and remaining noodles, broken to fit. Top with remaining tomato sauce mixture; cover with lid.
• Cook on LOW 4 to 6 hours. Sprinkle with remaining cheeses; let stand, covered, 10 min. or until shredded cheese is melted.

Steps:

• Stir the ricotta, spinach, mushrooms, parsley, 1/2 teaspoon salt and a few grinds of pepper in a large bowl. In a medium bowl, combine the mozzarella and parmesan.
• Spread about 1/2 cup marinara sauce in a thin layer in a 6-quart slow cooker. Cover with a single layer of uncooked lasagna noodles (4 to 6 noodles), breaking them as needed to fit. Spread half of the ricotta mixture over the noodles. Top with about one-third of the remaining sauce, then sprinkle with about one-third of the mozzarella mixture. Repeat the layers (noodles, ricotta, sauce, mozzarella mixture). Top with the remaining noodles, then the remaining sauce and mozzarella mixture.
• Cover and cook on low, 4 hours. Uncover and let rest 15 minutes so the excess liquid is absorbed.

Steps:

• In a large bowl, stir together the ricotta, spinach, Parmesan, basil, garlic, oregano, onion powder, ¼ teaspoon salt and a generous amount of black pepper.
• Lightly grease the bottom and sides of a 6- to 7-quart slow cooker with olive oil. Ladle about 1 cup of the marinara sauce in the bottom of the slow cooker, and spread it evenly.
• Make two layers: Lay 3 lasagna noodles on top of the sauce, breaking the noodles to make a roughly even layer. (This doesn't need to be perfect; it's fine if the noodles overlap slightly, and if there are small spots the noodles don't cover.) Ladle about ¾ cup of sauce on top of the noodles and spread evenly. Evenly dollop about half of the ricotta mixture over the sauce, and use the back of a fork to press it into a roughly even layer. Sprinkle about a third of the shredded mozzarella over the ricotta. Repeat to make one more layer, using three noodles, the ¾ cup sauce, the remaining half of the ricotta mixture, then about half of the remaining mozzarella.
• To finish, lay down the remaining 3 lasagna noodles and spread with the remaining sauce. (Reserve the remaining mozzarella.) Cover and cook on low until the internal temperature in the center is at least 140 degrees and the noodles are tender, 3 hours 30 minutes to 4 hours.
• Turn off the slow cooker and sprinkle the top of the lasagna with the remaining mozzarella. Remove the crock from the base that contains the heating element and let the lasagna rest with the lid on for 20 to 30 minutes, otherwise it will fall apart when you try to slice it. Sprinkle the top with more torn basil, to your taste. Cut the lasagna with a knife and scoop out servings with a spatula to serve.

Steps:

• Wilt spinach in a saucepan with a few tablespoons of water. Drain, squeeze dry, and coarsly chop. Combine spinach, mushrooms, and pesto in a medium bowl, set aside. Combine mozzarella, provolone, ricotta, beaten egg, and stir well. Stirl in 1/4 cup parmesan, set aside. Combine pasta sauce, tomato sauce, tomato paste. Spread 1 cup of pasta sauce mixture in the bottom of a slow cooker. Arrange 3 noodle over pasta sauce, top with 1 cup cheese mixture and 1 cup spinach mixture. Repeat with layers, ending with spinach mixture each time, and last layer is just noodles and pasta sauce. Sprinkle with remaining parmesand cover with lid, cook on low for 5 hours or until done. 8 servings.

Steps:

• Spray 5- to 6-quart slow cooker with cooking spray. In medium bowl, mix pasta sauce, tomatoes, crushed red pepper, bell pepper and zucchini. Spread 1 cup tomato mixture in bottom of slow cooker.
• Layer 3 lasagna noodles, broken into pieces to fit, over sauce in slow cooker. Spread half of the ricotta cheese over noodles; sprinkle with 1/4 cup of the mozzarella cheese and half of the spinach. Top with one-third of the tomato sauce mixture (about 1 1/2 cups). Repeat layering of noodles, cheeses and spinach. Top with remaining 3 noodles and sauce. Save remaining 1 cup mozzarella cheese in refrigerator.
• Cover; cook on Low heat setting 4 to 5 hours or until noodles are tender and cooked through. Sprinkle with reserved mozzarella; cover and let stand 10 minutes to melt cheese.
