One Pot Spinach Mushroom Lasagna Recipes

VEGETARIAN SPINACH AND MUSHROOM LASAGNA

Steps:

• Preheat the oven and prep the pan: Preheat the oven to 350°F. Spread the one cup of reserved tomato sauce over the bottom of a large (preferably 10- x 15-inch) casserole dish. (If your casserole dish is smaller, you may need to add another layer as you go through this step.)
• Cover with foil and bake: Pull out a sheet of aluminum foil large enough to cover the casserole dish. Spread a little olive oil over the inside of the piece of foil (the side that will have contact with the lasagna). Place the foil over the casserole dish and crimp the edges. Bake at 350°F for 25 minutes, then remove the foil and bake uncovered for an additional 25 minutes. Take the lasagna out of the oven when done and let it rest 10 minutes before cutting to serve. Once made, the lasagna will last a week in the fridge.

CREAMY SPINACH AND MUSHROOM LASAGNA

Steps:

• Preheat oven to 350 degrees F. To make the sauce, melt butter in a saucepan over medium heat. Add garlic, mushrooms and onion. Cook, stirring occasionally, until tender, about 3-4 minutes. Whisk in flour until lightly browned, about 1 minute. Gradually whisk in milk, and cook, whisking constantly, until slightly thickened, about 2-3 minutes. Stir in basil, oregano and nutmeg until fragrant, about 1 minute; season with salt and pepper, to taste; set aside. In a large pot of boiling salted water, cook lasagna noodles according to package instructions. Spread 1 cup mushroom sauce onto the bottom of a 9×13 baking dish; top with 3 lasagna noodles, 1/2 of the ricotta cheese, 1/2 of the spinach, 1 cup mozzarella cheese and 1/4 cup Parmesan. Repeat with a second layer. Top with remaining noodles, mushroom sauce and cheeses.* Place into oven and bake for 35-45 minutes, or until bubbling. Then broil for 2-3 minutes, or until top is browned in spots. Let cool 15 minutes. Serve, garnished with parsley, if desired.

SPINACH AND MUSHROOM LASAGNA

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.

SPINACH LASAGNA WITH MUSHROOM RAGU

Steps:

• Make the ragu: Soak the porcini mushrooms in 1 cup hot water until soft, about 15 minutes. Strain through a fine-mesh sieve over a bowl. Chop; reserve the liquid.
• Meanwhile, heat the olive oil in a pot over medium heat. Add the onion, carrot and celery and cook until soft, 5 minutes. Stir in the garlic and tomato paste and cook, stirring, 2 more minutes. Add the portobello and shiitake mushrooms, 1 teaspoon salt and 1/2 teaspoon pepper; cook, stirring, until the mushrooms are soft, 5 more minutes.
• Add the porcini mushrooms; cook 2 minutes. Add the reserved porcini liquid, bring to a boil and cook until reduced slightly, about 3 minutes. Add the tomatoes and their juice, 2 cups water and the bay leaves; bring to a boil, stirring occasionally. Reduce the heat to medium low, add the parsley and 1 teaspoon salt and simmer, stirring a few times, until thick, about 1 hour, 30 minutes. Discard the bay leaves. (You can make the ragu up to 1 day ahead; let cool, then cover and chill. Reheat before using.)
• Make the lasagna filling: Mix the parmesan, mozzarella and asiago; set 1 1/2 cups of the cheese mixture aside. Combine the remaining cheese mixture in a large bowl with the ricotta, eggs, spinach, nutmeg and 1/2 teaspoon salt.
• Preheat the oven to 375 degrees F. Bring a pot of salted water to a boil. Add the noodles and cook as the label directs. Drain and rinse under cold water; shake off the excess water.
• Spread 1 cup of the ragu in a 9-by-13-inch baking dish. Add a layer of noodles, then half of the spinach mixture and 2 cups ragu. Repeat with another layer of noodles, spinach mixture and ragu. Top with the remaining noodles and ragu and sprinkle with the reserved cheese. Cover with foil, place on a baking sheet and bake 50 minutes. Uncover and bake until golden, about 25 more minutes. Let rest before serving.

INSTANT POT SPINACH AND MUSHROOM LASAGNA

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.

SPINACH LASAGNA III

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• Bring a large pot of lightly salted water to a boil. Add lasagna noodles and cook for 8 to 10 minutes or until al dente; drain.
• In a skillet over medium-high heat, cook mushrooms, onions, and garlic in olive oil until onions are tender. Drain excess liquid and cool. Boil spinach for 5 minutes. Drain, then squeeze out excess liquid. Chop spinach.
• Combine ricotta cheese, Romano cheese, spinach, salt, oregano, basil, pepper, and egg in a bowl. Add cooled mushroom mixture. Beat with an electric mixer on low speed for 1 minute. Lay 5 lasagna noodles in bottom of a 9x13 inch baking dish. Spread one third of the cheese/spinach mixture over noodles. Sprinkle 1 cup mozzarella cheese and 1/3 cup Parmesan cheese on top. Spread 1 cup pasta sauce over cheese. Repeat layering 2 times.
• Cover dish with aluminum foil and bake in a preheated oven for 1 hour. Cool 15 minutes before serving.

QUICK MUSHROOM & SPINACH LASAGNE

Steps:

• Heat oven to 200C/180C fan/gas 6. Heat the oil in a large frying pan, add the garlic and cook for 1 min. Add the mushrooms and thyme, then cook for 3 mins until they start to soften. Throw in the spinach and stir until the heat of the pan wilts the leaves. Remove from the heat and stir in the soft cheese, 1 tbsp of the Parmesan and some seasoning.
• Put a quarter of the spinach mix on the bottom of a medium-sized baking dish, lay 2 pasta sheets on top, then repeat until you have used all the pasta. Finish with the final quarter of the spinach mix, sprinkle over the rest of the Parmesan, then bake for 35 mins until golden and the pasta is tender.

CREAMY MUSHROOM LASAGNE

Steps:

• For the ragu, put the dried porcini mushrooms in a heatproof mug and cover with 125ml boiling water from the kettle. Set aside. Finely chop the chestnut mushrooms or blitz in a food processor to fine pieces.
• Heat the oil in a large saucepan or flameproof casserole over a high heat and fry the onions, carrots and chopped chestnut mushrooms with a pinch of salt for 15 mins until the water released by the mushrooms has evaporated, stirring now and then. The mushrooms should be a deep brown colour and the other veg should be soft and slightly coloured.
• Add the mixed mushrooms, garlic and most of the thyme, and cook for another 5 mins until the mushrooms have started to soften. Drain the rehydrated porcini, add the soaking liquid to the pan, then finely chop the porcini and add that too. Stir in the wine, passata, ketchup and paprika to combine. Simmer for 25 mins until the ragu has reduced and is thick enough to coat the back of a spoon. Season generously with sea salt flakes and a grinding of black pepper.
• Meanwhile, make the béchamel. Melt the butter in a saucepan over a medium heat, then add the bay and cook for a minute. Scatter in the flour and stir until you have a sticky paste. Add the milk in stages, whisking between each addition until you have a thick sauce. Reduce the heat to low and cook for 3-4 mins, stirring occasionally until the sauce is thick enough to coat a spoon. Remove the bay, then mix in the crème fraîche, a generous grating of nutmeg and seasoning.
• Heat the oven to 200C/180C fan/gas 6. Rub the olive oil over the base and sides of a large ceramic baking dish (ours was 35 x 20 x 6cm). Arrange a layer of lasagne sheets in the base (you may need to break them so they fit), then spoon over a layer of the mushroom ragu, drizzle with some of the béchamel, and scatter over a handful of the mozzarella. Repeat until you have used all the ragu and the final layer of lasagne sheets, then smooth over a thick layer of béchamel. Sprinkle over the remaining mozzarella and bake for 40-45 mins until the filling is bubbling and the top is golden. Leave to rest for 10 mins, then sprinkle with the remaining thyme leaves before serving.
