Ingredients

  • 12 oz Ziti or similar pasta shape such as penne
  • 6 oz chopped frozen spinach thawed, and squeezed out
  • 8 oz ricotta cheese
  • 4 cups marinara sauce approx 3x 14oz jars
  • 14 oz canned lentils drained and rinsed - approx 1.5 cups lentils
  • 2 ½ cups shredded mozzarella cheese divided

Instructions

  • Preheat your oven to 350°F / 180°C. Set a large pot of water over high heat to come to a boil.
  • Start by squeezing as much moisture as possible from your frozen spinach. I like using a clean kitchen towel for this job (pictured above).
  • Mix the spinach into the ricotta, and season with salt and pepper. Set aside.
  • Boil your pasta in a large pot of salted water until al dente. This typically takes about 8-10 minutes, but varies from brand to brand and shape to shape. Drain the pasta, then return to the same pot.
  • Reserve about ¾ cup of pasta sauce for the baking dish. Add remaining 3 ¼ cups marinara sauce, lentils, and ½ cup of mozzarella cheese to the pasta. Stir to combine.
  • Pour ¾ cup of reserved marinara sauce into the bottom of your casserole dish, and spread out in a thin layer.
  • Add about half of the pasta to the dish, and spread out in an even layer.
  • Dollop heaping tablespoons of the ricotta mixture over the top of the pasta.
  • Add the remaining pasta, and then the remaining ricotta mixture. Use a spoon to gently tuck the ricotta into the pasta as best as possible.
  • Scatter the remaining 2 cups cheese over the top of the pasta dish.
  • Cover the casserole dish with foil (or use an oven-proof lid if it comes with one) and bake for 30 minutes.
  • Remove the foil, and bake for an additional 10 minutes, until the cheese is brown and bubbly on top.

Notes

  • Nutrition values are an estimate only
  • Note that I measured pasta sauce and lentils in cups as jars and cans come in different sizes.
  • If you prefer to cook your own lentils rather than using cans, start with ½ cup green or brown lentils, and cook until tender. 
  • To make this dish gluten-free, simply substitute gluten-free pasta
  • This dish can be made in advance, up to the point of baking, and then refrigerated for up to 2 days or freeze, tightly covered, for up to 3 months.
