Recipe Background

This 4-Ingredient Casserole, including ravioli and marinara, is perfect for marking special goodbyes.
When my best friend decided to move across the country, we marked her last night in town with a low-key evening at my place, making something easy yet comforting: a 4-Ingredient Casserole. I remember standing in the kitchen, eyeing a trusty package of cheese ravioli. Underneath, I could almost feel her nerves and excitement about the journey ahead. With a quick scan of my pantry, I grabbed a jar of marinara sauce. For a bit of color and surprise, I pulled out a frozen bag of spinach, because, why not? The thawing and squeezing of the spinach made us laugh at how adulting is just a series of these small, practical miracles.
As we layered the ravioli with the mozzarella and marinara, we chatted about how this cheesy goodness mirrored her upcoming adventure—simple, but full of flavor. I showed her a little trick: let the dish stand for a bit after baking to make serving a breeze. It turned out to be a magical evening, bubbling with memories and mozzarella alike. I still recall how she snapped a picture before the first slice, capturing both a tasty dinner and the mutual realization that goodbyes aren't always sad.
That casserole became more than just a meal. It's a little culinary landmark of friendship and warmth, made with just a few ingredients and a lot of love. I'll always keep it as my go-to for moments that call for something easy, delightful, and deeply satisfying.

Ingredients

  • 2 1/2 cups marinara sauce
  • 1 (24-ounce) package frozen cheese ravioli
  • 1 (8-ounce) package frozen spinach optional, thawed and squeezed-dry
  • 2 cups mozzarella cheese shredded
  • 1/4 cup parmesan cheese grated

Directions

  • Preheat the oven to 400 degrees F.
  • Spray a 9x13-inch baking dish with cooking spray.
  • Pour a thin layer, about 1/2 cup, of the marinara sauce to cover the bottom of the prepared baking dish.
  • Arrange 1/2 of the frozen ravioli in a single layer over the sauce.
  • Layer the spinach on the ravioli, if using.
  • Add 1/2 of the marinara and 1/2 of the mozzarella in even layers in the baking dish.
  • Repeat the layers of the ravioli, the sauce, and the mozzarella once, starting with the ravioli.
  • Sprinkle the parmesan cheese on top.
  • Cover the baking dish with aluminum foil and bake for 20 minutes.
  • Remove the foil and bake, uncovered, until bubbly and hot in the center, about 20-25 minutes.
  • Let stand for 10 minutes.
  • Serve.
