Categories     Spinach

Time 1h15m

Yield 4 serving(s)

Number Of Ingredients 13

5 red peppers, thickly sliced
2 tablespoons olive oil
2 tablespoons balsamic vinegar
3 garlic cloves, finely chopped
8 ounces fresh Baby Spinach
5 ounces fresh lasagna noodles, prepared according to packet instructions
10 ounces mozzarella cheese, thickly sliced
2 1/2 cups milk
1 bay leaf
2 ounces butter
1 1/2 ounces flour
1 teaspoon Dijon mustard
5 ounces parmesan cheese, grated

Steps:

  • Preheat the oven to 350°F Place the peppers in a roasting tin and drizzle with the oil and balsamic vinegar. Roast for 20 minutes, add the garlic and roast for a further 10 minutes until the peppers are softened and charred.
  • Meanwhile, wilt the spinach in a large pan with a splash of water for 2 minutes only. Season well and set aside.
  • To make the sauce, heat the milk with the bay leaf to just below boiling point and simmer gently for 5 minutes. Melt the butter in a non-stick pan, add the flour and cook, stirring all the time, for 2 minutes. Gradually add the milk, whisking well, and bring to the boil until thickened. Stir in the mustard and half of the Parmesan.
  • To layer up the lasagna, spoon a third of the sauce into the base of an ovenproof dish. Scatter over half of the peppers, half of the spinach and half of the mozzarella. Top with a layer of lasagna. Repeat this process, finishing with the final third of the sauce. Scatter over the remaining Parmesan and bake for 25 to 30 minutes.

SLOW-COOKER LASAGNA



Slow-Cooker Lasagna image

This easy slow-cooker lasagna is satisfying in all the ways that matter: Rich ricotta-Parmesan-spinach layers alternate with tender noodles, melted mozzarella and tomato. (A slow cooker will not give the crispiness that an oven does, but you may not even miss it.) It's also petite compared to many other lasagnas, perfect for feeding a family, not a crowd. If you've ever had a one-pot pasta, the texture of the noodles will be familiar to you: They are tender and starchy. Don't use no-boil or fresh noodles, as they will overcook. If you like, brown some loose Italian sausage in a skillet, pour off the fat and add it with the tomato sauce layers.

Time 4h10m

Yield 4 to 6 servings

Number Of Ingredients 12

1 pound whole-milk ricotta cheese (about 2 cups)
1 (10-ounce) bag or box frozen spinach, thawed and squeezed dry
3 ounces finely grated Parmesan (about 1 scant cup)
1/2 cup lightly packed, roughly chopped basil leaves, plus more for topping
5 garlic cloves, grated or pressed
1 teaspoon dried oregano
1 teaspoon onion powder
Kosher salt and black pepper
Olive oil
1 (32-ounce) jar good-quality marinara sauce
9 lasagna noodles (7 to 8 ounces)
8 ounces shredded mozzarella (2 cups)

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.

Tips:

  • Use a variety of bell peppers for a more colorful lasagna. Orange, yellow, and purple bell peppers would all be great additions.
  • If you don't have spinach on hand, you can substitute kale or Swiss chard. Just be sure to wilt the greens before adding them to the lasagna.
  • Use a good quality ricotta cheese for the best flavor. Fresh ricotta is always best, but if you can't find it, use a high-quality store-bought brand.
  • Don't be afraid to add some extra spices to the lasagna. A pinch of red pepper flakes or a teaspoon of dried oregano would both be great additions.
  • Let the lasagna rest for at least 15 minutes before serving. This will help the flavors to meld and the lasagna to set.

Conclusion:

This slow cooker red pepper spinach lasagna is a delicious and easy weeknight meal. It's packed with flavor and is sure to be a hit with the whole family. So next time you're looking for a quick and easy dinner, give this lasagna a try. You won't be disappointed!
