One Pot Spinach Mushroom 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:

• 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:

• Preheat oven to 350 degrees F.
• Cook the lasagna noodles according to the package directions; drain, rinse immediately with cold water and then drain again; toss with 1 Tbsp olive oil and set aside.
• Melt 2 tablespoon butter in a large sauté pan over medium-high heat; add the mushrooms and cook until golden, about 5 minutes.
• Reduce heat to medium and add the green onions, shallots, and garlic, and sauté for 3 minutes.
• Add the drained, chopped spinach, white pepper, and salt, stir well and sauté for an additional 5 minutes.
• Transfer the mushroom/spinach mixture to a bowl and set aside (do not rinse out this pan - we're going to use it again in the upcoming steps).
• Over medium heat melt the remaining butter in the previously-used saucepan; add the flour and cook, stirring constantly to keep it from browning.
• Gradually add the chicken or vegetable broth, cream, and vermouth; cook, stirring occasionally, until smooth and thickened, about 5 minutes.
• As soon as sauce begins to boil, remove it from the heat and season with thyme and basil.
• Combine the shredded cheeses together until well mixed.
• Butter, oil, or lightly spray the bottom of a 9x13-inch baking pan.
• Pour the half-and-half into the bottom of the baking pan.
• Lay 4 cooked noodles in a single layer in the pan.
• Layer with 1/3 each of the mushroom/spinach mixture and shredded cheeses, then coat with 1/3 of the sauce.
• Repeat the process twice, ending with the sauce.
• Sprinkle with grated Parmesan (if using).
• Cover the pan with foil and bake at 350F for 20 minutes, then remove foil and bake 20 minutes longer.
• Remove from oven and let sit 15 minutes before serving.
• Makes 8 to 10 servings.

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:

• Heat oil in a large skillet over medium-high heat. Add mushrooms and cook until softened, about 5 minutes. Add red pepper flakes and spinach, cooking until spinach is wilted.
• Stir in Ragu® Sauce and water. Bring to a boil. Stir in uncooked noodles. Reduce heat to medium and cook covered until noodles are tender, about 20 minutes. Note: be sure to stir frequently so the noodles do not settle at the bottom of the pan.
• Top noodles with spoonfuls of ricotta cheese and then sprinkle with mozzarella cheese. Reduce heat to a simmer and cook covered until cheese is melted (about 5 minutes). Sprinkle with grated Parmesan cheese, if desired.

Steps:

• Preheat oven to 350 degrees. Coat a large baking dish with cooking spray. Put a large pot of water on to boil.
• Cook noodles in boiling water until not quite al dente, about 2 minutes less than package directions. Drain; return the noodles to the pot, cover with cool water and set aside.
• Coat a large nonstick skillet with cooking spray and heat over medium-high heat. Add sausage and cook, crumbling with a wooden spoon, until browned, about 4 minutes. Add mushrooms and water; cook, stirring occasionally and crumbling the sausage more, until the sausage is cooked through, the water has evaporated and the mushrooms are tender, 8 to 10 minutes. Stir spinach into pan; remove from heat.
• Mix tomatoes with basil, salt and pepper in a medium bowl.
• To assemble lasagna: Spread one-fourth of the tomatoes in prepared baking dish. Arrange a layer of noodles on top, trimming to fit if necessary. Evenly dollop half the cottage cheese over the noodles. Top with half the sausage mixture, one-third of remaining tomatoes and one-third of remaining mozzarella. Continue with another layer of noodles, the remaining cottage cheese, the remaining sausage, half the remaining tomatoes, and half the remaining mozzarella. Top with a third layer of noodles and remaining tomatoes.
• Cover the lasagna with foil and bake until bubbling and heated through, 1 hour to 1 hour and 10 minutes. Remove the foil and sprinkle the remaining mozzarella on the lasagna. Return to the oven and bake until the cheese is just melted but not browned, 8 to 10 minutes. Let rest for 10 minutes before serving.
