Why You'll Love This Recipe
Cauliflower steaks make this feel substantial: sliced thick so they hold up under all that sauce and cheese without turning to mush.
The pesto layer is the secret: spooned over the meat sauce before the cheese goes on, it adds a bright herby freshness that makes every bite taste more interesting.
Broiled at the end: 40 minutes covered makes the cauliflower perfectly tender and 3 minutes under the broiler makes the cheese bubbly and golden.
One baking dish feeds five: make it ahead, reheat it during the week, and it tastes just as good the next day.

Ingredient Notes
Cauliflower Steaks: Cutting the cauliflower into steaks rather than florets is what makes this dish feel like a proper meal rather than a side dish. The flat surface of each steak absorbs the sauce and the cheese from above and gives you a completely different texture than roasted florets.
Italian Chicken Sausage: Italian chicken sausage is leaner than pork but still brings all that fennel and herb flavor that makes Italian sausage so good in a marinara. That caramelized crust on the sausage adds a depth of flavor to the whole sauce that you simply cannot get if you stir it too early. The same technique I use in my Sausage and Mushroom Orzo and it makes all the difference.
Marinara Sauce: Use a good one because it is doing a lot of the flavor work in this dish. Look for a jar that lists tomatoes as the first ingredient and uses olive oil rather than vegetable oil.
Pesto: It adds a bright, herby, garlicky note that cuts through the richness of the marinara and the cheese and makes every bite taste more interesting. Store-bought pesto works beautifully here, though homemade is always better 🙂
Mozzarella and Parmigiano Reggiano: Two cheeses, two jobs. Mozzarella gives you that classic stretchy, melty layer that holds everything together. Parmigiano Reggiano adds a deep nutty, savory richness on top that mozzarella alone cannot give you. I use the same combination in my Mushroom and White Sauce Puff Pastry Pizza for the same reason.
Pro tip
The Secret to A Perfect Bake
Do not skip the broil. The 40-minute covered bake cooks everything through, but the 3-minute broil is what takes the cheese from melted to bubbly, golden, and slightly crispy at the edges.
Substitutions & Variations
No chicken sausage? Pork Italian sausage works beautifully here and will give you even more flavor. Turkey sausage is another lighter option. Just make sure whatever you use has the casings removed before cooking.
No pesto? A drizzle of good extra virgin olive oil and a handful of fresh basil torn over the sauce before the cheese goes on gives you a similar herby brightness. Not identical but still very good.
Want to add more vegetables? Sliced zucchini or bell peppers layered alongside the cauliflower steaks add color and more Mediterranean character to the dish. Just make sure they are cut to a similar thickness so everything cooks evenly.
Want to make it spicier? Double the red pepper flakes in the sauce or add a tablespoon of Calabrian chili paste with the marinara. The heat works beautifully against the creamy melted cheese. If you love Calabrian chili in a baked dish, my Sheet Pan Meatballs and Vegetables uses it to great effect.
FAQ
Yes, completely normal. Cauliflower contains a lot of water that releases during the long covered bake.
Yes. Assemble the entire dish up to the cheese layer, cover tightly and refrigerate for up to 24 hours. Add the cheese right before baking. You may need to add 5 to 10 extra minutes to the covered bake time since it is going in cold.

Cauliflower & Chicken Sausage Bake
Ingredients
Meat sauce
- 1 lb Italian chicken sausage casings removed
- 24 oz jar marinara sauce
- ½ white onion diced
- 3 garlic cloves crushed
- 1 tablespoon extra virgin olive oil
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon red pepper flakes
- ½ teaspoon paprika
- ½ teaspoon salt
Bake
- 2 heads of cauliflower cut into 6-7 one inch-thick steaks
- 5 tablespoon pesto store bought or homemade
- 2 cups shredded mozzarella cheese
- ½ cup freshly grated Parmigiano Reggiano
Instructions
Make the meat sauce
- Heat the olive oil in a large skillet over medium high heat. Add the chicken sausage with the casings removed and spread it out across the pan. Let it cook completely undisturbed for 3 to 4 minutes until a deep golden brown sear develops on the bottom. Do not stir it. That sear is where the flavor lives.1 lb Italian chicken sausage, 1 tablespoon extra virgin olive oil
- Break the sausage into crumbles and add the diced onion. Cook for 2 to 3 minutes until the onion softens and becomes translucent. Add the crushed garlic and cook for 30 seconds stirring constantly so it does not burn.½ white onion, 3 garlic cloves
- Add the Italian seasoning, garlic powder, onion powder, red pepper flakes, paprika, and salt. Stir to coat the sausage and onion mixture evenly in the spices.1 teaspoon Italian seasoning, 1 teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon red pepper flakes, ½ teaspoon paprika, ½ teaspoon salt
- Pour in the marinara sauce and stir to combine. Let it simmer over medium low heat for 3 to 4 minutes until the sauce has thickened slightly and the flavors have come together. Taste and adjust salt and red pepper flakes as needed.24 oz jar marinara sauce
Prep the cauliflower
- Preheat your oven to 400F. Remove the outer leaves from the cauliflower and trim the base of the stem slightly so it sits flat on the cutting board. Starting from the center of the head, cut straight down through the stem into inch-thick slabs. You should get 8 steaks, depending on the size of your heads. Some florets on the outer edges may fall away. Save those and tuck them around the steaks in the baking dish.2 heads of cauliflower
Build the baking dish
- Spoon a thin layer of the meat sauce across the bottom of a large baking dish. This prevents the cauliflower from sticking and ensures the bottom of each steak stays moist and flavored during the bake.
- Arrange the cauliflower steaks in a single layer over the sauce. Spoon the remaining meat sauce generously over each steak, making sure every surface is covered. Then spoon the pesto evenly over the meat sauce layer. The cauliflower will release some liquid during baking, and that is completely normal.5 tablespoon pesto
Add the cheese and bake
- Scatter the shredded mozzarella evenly over the top then finish with the freshly grated Parmigiano Reggiano. Cover the baking dish tightly with aluminum foil. Bake at 400F for 40 minutes until the cauliflower is fork tender all the way through. To check, insert a knife or skewer into the thickest part of a steak. It should slide through with no resistance.2 cups shredded mozzarella cheese, ½ cup freshly grated Parmigiano Reggiano
Broil
- Remove the foil and switch the oven to broil. Broil for 3-4 minutes until the cheese is bubbly, golden, and slightly crispy at the edges. Watch it closely. The difference between perfect and burnt is about 60 seconds under a broiler. Remove from the oven and let rest for 2 minutes before serving.
Serve
- Use a large spatula to lift each cauliflower steak carefully onto the plate. Spoon any remaining sauce and cheese from the dish over the top. Serve immediately while the cheese is still bubbly and the cauliflower is hot.
