Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 40 minutes
• Total Time: 1 hour
• Servings: 6-8
• Dietary Type: Gluten-Free (with gluten-free breadcrumbs)

Ingredients

• 2 tablespoons olive oil
• 1 lb bulk sweet Italian sausage
• 1 medium white onion, diced small
• 4 garlic cloves, minced
• 1 medium head cauliflower (about 2 pounds, cut into small florets)
• 1 (28 ounce) can whole Italian tomatoes (crushed and broken up with your hands)
• 1 cup chopped Italian parsley, divided
• 2⁄3 cup panko breadcrumbs
• 1⁄4 cup grated Parmesan cheese
• Salt, pepper to taste

Equipment Needed

• Large Dutch oven
• 13×9 inch baking dish
• Small mixing bowl

Instructions

1. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). This ensures the casserole bakes evenly and the topping gets perfectly golden brown.

2. Heat a large Dutch oven over medium-high heat. Add the 2 tablespoons of olive oil. Once the oil is shimmering, add the 1 lb of sweet Italian sausage and diced white onion. Cook, breaking up the sausage with a spoon or spatula as you go, for about 10 minutes. The sausage should be browned, and the onions softened. Add the minced garlic halfway through the cooking time (around minute 5) to prevent it from burning.

3. Remove the sausage and onion mixture from the Dutch oven and set aside in a bowl. Don’t discard any flavorful rendered fat left in the pot; it will add depth to the cauliflower.

4. Add the cauliflower florets to the reheated Dutch oven. Brown the florets on all sides, about 2 to 3 minutes per side. Season generously with salt and freshly ground black pepper to taste. Don’t overcrowd the pot; work in batches if necessary to ensure proper browning. Browning the cauliflower before baking intensifies its flavor and adds a pleasant textural element.

5. Add the crushed Italian tomatoes (with their liquid) to the Dutch oven, along with the cooked sausage and onion mixture. Bring the mixture to a simmer and then reduce the heat to low. Adjust the seasoning with additional salt and pepper as needed. The sauce should be slightly thicker than a soup, but not too dry.

6. Stir in half (1/2 cup) of the chopped Italian parsley into the sausage and cauliflower mixture. This infuses the casserole with fresh, herbaceous flavor.

7. Transfer the mixture to a 13×9 inch baking dish. Spread it evenly across the bottom of the dish.

8. In a small bowl, combine the panko breadcrumbs, grated Parmesan cheese, and remaining half (1/2 cup) of the parsley. Mix well. This creates a crispy, flavorful topping for the casserole.

9. Sprinkle the panko mixture evenly over the top of the sausage and cauliflower mixture in the baking dish. Make sure to cover the entire surface for maximum crunch.

10. Bake in the preheated oven for about 30 minutes, or until the topping is golden brown and crispy. The casserole should be bubbling around the edges, indicating that it’s heated through.

11. Remove the casserole from the oven and let it sit for 5 to 10 minutes before serving. This allows the flavors to meld together and the casserole to set slightly, making it easier to serve.

Expert Tips & Tricks

• For extra flavor, try using a combination of sweet and hot Italian sausage. The spice adds a wonderful kick that complements the sweetness of the tomatoes and cauliflower.
• Don’t be afraid to experiment with other vegetables. Bell peppers, mushrooms, or zucchini would all be delicious additions to this casserole.
• If you’re short on time, you can use pre-cut cauliflower florets. Just make sure they are roughly the same size for even cooking.
• To prevent the panko topping from burning, cover the casserole with foil during the last 10 minutes of baking.
• Make ahead tip: Assemble the casserole up to the baking step. Cover tightly with plastic wrap and refrigerate for up to 24 hours. Add about 10 minutes to the baking time when cooking from cold.

Serving & Storage Suggestions

Serve the Cauliflower-Italian Sausage Casserole hot, straight from the oven. It’s delicious on its own, but also pairs well with a simple green salad or a slice of crusty bread for soaking up all the delicious sauce.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions until heated through, or reheat the entire casserole in a preheated oven at 350°F (175°C) until warmed through. The topping may lose some of its crispness upon reheating.

For longer storage, the casserole can be frozen for up to 2 months. Thaw completely in the refrigerator before reheating.
