How To Make Parmesan Cauliflower Steaks with Marinara

Have a healthy yet filling dinner with these cauliflower steaks tossed with parmesan and spices then topped with marinara sauce and whole-grain spaghetti.

Preparation: 10 minutes
Cooking: 40 minutes
Total: 50 minutes



For the Cauliflower Steaks:

  • 1headcauliflower,large
  • 3tbspolive oil
  • 1ozParmesan cheese,finely grated, about ¾ cup
  • salt and freshly ground black pepper

For the Garnish and Sauce:

  • 8ozwhole grain spaghetti,DeLallo Organic Whole Wheat Spaghetti recommended
  • 25ozmarinara sauce,jar, DeLallo Pomodoro Fresco Marinara Sauce recommended
  • grated Parmesan,or pepper, and/or pinch red pepper flakes, optional garnishes


  1. Preheat oven to 425 degrees F and line a large baking sheet with parchment paper. Turn the cauliflower on its side and slice off the protruding end of the stem.

  2. Place the cauliflower on a cutting board with the floret side up and use a sharp knife to slice it into 1-inch thick slices.

  3. Transfer the cauliflower to your prepared baking sheet. Drizzle on two tablespoons of olive oil and gently toss to coat.

  4. Rub the oil onto all sides of the cauliflower until all pieces are lightly coated, adding more oil if necessary.

  5. Sprinkle the cauliflower with salt and pepper. Arrange it in a single layer and roast for 20 minutes.

  6. Remove the cauliflower from the oven and carefully flip the cauliflower.

  7. Sprinkle the Parmesan over the cauliflower and return it to the oven for another 18 to 20 minutes until the Parmesan is golden and the cauliflower is tender and caramelized on the edges.

  8. Meanwhile, bring a large, salted pot of water to boil. Add the spaghetti and cook until al dente, according to package directions. Drain and toss with a light drizzle of olive oil to prevent sticking.

  9. Warm the sauce in a medium saucepan on the stove. Cover and maintain a gentle simmer until you’re ready to serve.

  10. Divide the spaghetti into individual bowls or plates, top with ample marinara sauce and roasted cauliflower.
