Classic Lasagna
with Italian sausage / kale

Active: 40 Total: 90
Over the years we've received requests for a lasagna recipe, but never created one - until now. With oven-ready (no-boil) noodles and the ability to prep the layers (or assemble the entire dish) ahead, this lasagna takes a bit longer than our typical meal but still has a lightened-up, vegetable-packed Cook Smarts twist.
Smarts #1: Make this in an 8x8 pan for 4 servings. If customizing, try scaling down in a loaf pan or scaling up to a rectangular casserole dish.
Smarts #2: We included plenty of vegetables in the lasagna itself, but if you want a side dish, this would be great with garlic bread or a simple green salad.

Prep

  1. Kale - Remove and discard stems. Chop leaves. (Can be done up to 5 days ahead)
  2. Mushrooms - Chop mushrooms, if not pre-chopped. (Can be done up to 5 days ahead)
  3. Make sauce - Heat olive oil in a Dutch oven over medium-high heat. Add sausage and saute, breaking it apart, until browned in spots and nearly cooked through, 6 to 7 minutes. Stir in kale leaves and mushrooms and saute for 5 minutes more. Stir in Italian seasoning and tomato paste. Pour crushed tomatoes and water over sausage and reduce heat to a low simmer. Cover with a lid and simmer for 15 minutes to let the flavors develop. Taste and season with some salt, pepper, or some sugar (if you’d like the sauce to have a hint of sweetness). (Can be done up to 5 days ahead)
  4. Cheese (mozzarella and parmesan) - Prep as directed and store separately. (Can be done 1 day ahead)
  5. Make cheese layer - Combine ricotta, first portion of mozzarella, eggs, and nutmeg. (Can be done 1 day ahead)

Make

  1. Heat oven to 375F / 190C degrees. Spray an 8”x8” / 20cm x 20 cm square baking dish (adjust size if customizing) with nonstick cooking spray or brush with some oil.
  2. Spread a thin layer of sauce to cover the bottom of the pan.
  3. Top sauce with a single layer of lasagna noodles, then some cheese mixture, and then some sauce, repeating until all of the ingredients are used. Finish with a layer of noodles topped with sauce. (Note: Depending on the size of the noodles, you may need to break the noodles apart to make them fit and / or they may not reach all the way to the edges. Either of these is fine - even messy layers will cook into a delicious lasagna.)
  4. Cover the dish tightly with foil.
  5. Bake, covered, for 30 minutes.
  6. Take pan out of the oven and remove foil. Top lasagna with second portion of mozzarella and parmesan cheese.
  7. Continue baking, uncovered, until cheese is melted and golden, ~15 minutes more.
  8. Let lasagna rest for 5-10 minutes before slicing and serving. Enjoy!

I needed a wider dish. It was so thick with vertical layers and thus too much actual pasta. We omitted the egg. We really enjoyed the kale in it.

I love a good zucchini boat. I added cheese to half (I am not 100% Paleo all the time). Husband and I enjoyed it.

Very tasty - but needed much longer to cook then stated. Used spinach instead of kale and left out the mushrooms (because I loathe mushrooms). Used a really yummy sausage. Family loved it.

This was a delicious lasagna! I'm not a fan of mushrooms so I omitted them and just doubled the sausage. It was really good with garlic bread on the side!

doubled the seasoning. It cooked over in the oven. Would use a bigger pan next time. Flavors were outstanding.
