Keto Spicy Lasagna

November 23, 2020

Keto spicy lasagna in a white baking dish next to silver forks and Primal Kitchen Arrabbiata Sauce


The ultimate all-in-one dinner or lunch comfort food recipe, lasagna made with whole milk cheese, meat, acidic and fresh tomato sauce, and a spattering of green herbs is the epitome of Italian-style family food. It may be time intensive to prepare and bake, but it yields many returns of full-bellied satisfaction and leftovers whose flavors concentrate the longer they mingle. Our keto spicy lasagna recipe includes the expected oozing, tender layers of meat-cheese-sauce with a pleasant kick from crushed red chiles commingled with the sunshiny flavor of organic tomato paste and diced tomatoes in our arrabbiata sauce.

This spicy tomato sauce tastes like you've slaved over the back burner to make an old-fashioned spicy Italian gravy. Pair this sauce with ready-out-of-the-package hearts of palm lasagna sheets and you have an easy-to-make lasagna that tastes as nostalgic as the old-school way of pre-boiled pasta noodles layered with homemade pasta sauce, meat, and cheese—but only you need to know you took a couple of kitchen shortcuts.

Keto Spicy Lasagna Recipe

Time: 1 hour, 15 minutes

  • Preheat oven to 350ºF.

  • Spread 1 cup meat sauce onto bottom of 13x9-inch baking dish sprayed with cooking spray; top with layers of lasagna noodles, 1/3 of the ricotta mixture, and 1 cup of the remaining meat sauce. Repeat layers twice. Top with remaining noodles, meat sauce, and cheeses. Cover with lid.

  • Bake 1 hour or until heated through. Remove the lid of the dish after 45 minutes in the oven to bronze the cheese on top of the lasagna.
  • Remove from oven and let stand, partially covered, for 15 minutes before slicing.
  • Store any leftover lasagna in an airtight container in the refrigerator for up to 5 days. Freeze any extras by wrapping each slice of lasagna in parchment paper and storing in a resealable bag for up to 3 months.
