Ingredients You’ll Need

1 lb orzo: This pasta provides a hearty base for the casserole, soaking up all the delicious flavors while cooking.
4 cups vegetable broth: The broth adds depth and richness. Feel free to use low-sodium broth for a healthier option.
6 cloves garlic, minced: Freshly minced garlic gives the dish its signature aromatic quality.
1 tbsp Italian seasoning: This blend of herbs enhances the overall flavor profile.
1 tsp smoked paprika: Adding a subtle smokiness that rounds out the flavors.
¼ tsp each salt and ground black pepper: Essential for bringing all the ingredients to life. Adjust to taste.
1 8-oz block cream cheese: This creamy component adds richness and melty goodness to the casserole.
1 medium head cauliflower, cut into bite-sized pieces (about 4 cups): Cauliflower not only adds texture but also balances the dish without feeling heavy.
1 15-oz can butter beans, drained: These beans provide a creamy texture and additional protein. You can substitute any white bean you prefer.
½ cup finely grated Parmesan, grated from a block: Freshly grated Parmesan is ideal for optimal melting and flavor.

How to Make Garlic Parmesan Cauliflower Casserole

Prep the Oven and Dish: Preheat your oven to 375°F (190°C). Lightly grease a large (9×13 inch or similar) casserole dish to prevent sticking.
Combine Base Ingredients: In the prepared dish, combine 1 lb orzo, 4 cups vegetable broth, 6 cloves minced garlic, 1 tbsp Italian seasoning, 1 tsp smoked paprika, and ¼ tsp each salt and black pepper. Stir well to mix everything together.
Add Cream Cheese: Place the 8-oz block of cream cheese in the center of the mixture. Cover the dish tightly with aluminum foil to keep the moisture in during baking.
Initial Baking: Bake in the preheated oven for about 10 to 15 minutes. This will soften the cream cheese and heat the mixture. Remove the dish from the oven and remove the foil.
Mix in Vegetables and Beans: Stir the mixture well, breaking up the cream cheese until combined (it’s okay if some chunks remain as they will melt). Add 1 medium head of cauliflower and the 1 can of drained butter beans. Stir gently to mix everything together. Cover with foil again and return to the oven.
Complete Baking: Bake for an additional 25 to 30 minutes. The cauliflower should be fork-tender, and the orzo should be soft when ready. Taste the casserole and add salt if necessary.
Finish with Parmesan: Remove the foil, and sprinkle ½ cup finely grated Parmesan on top of the casserole. The cheese will melt slightly when it hits the warm dish. Serve immediately alongside crusty bread for a complete meal!

Storing & Reheating

To store leftover Garlic Parmesan Cauliflower Casserole, allow it to cool down to room temperature before transferring it to an airtight container. It can stay at room temperature for about an hour and should then be refrigerated for up to 3 days. For longer storage, freeze it in airtight containers for up to 3 months. When reheating, simply warm it in the oven at 350°F (175°C) for about 20 minutes or until heated through. Note that the texture may change slightly after freezing, but a splash of vegetable broth while reheating refreshes its creamy consistency.

Chef’s Helpful Tips

Avoid Overcooking the Cauliflower: Keep an eye on the cauliflower while it bakes. You want it tender but with a little bite—overcooking will lead to mushiness.
Use Fresh Parmesan: Grate your Parmesan from a block rather than using pre-grated cheese. Freshly grated cheese melts better and delivers a richer flavor.
Customize Your Beans: Feel free to swap the butter beans for another type of white bean, like cannellini or navy beans, depending on your taste.
Make Ahead: This dish can be assembled ahead of time and baked just before serving. Just remember to adjust cooking times as needed if it’s coming straight from the fridge!

Garlic Parmesan Cauliflower Casserole encapsulates the essence of cozy, satisfying food that’s perfect for gatherings or a weeknight dinner. Not only is it easy to prepare, but it’s also full of flavors that invite seconds.

Recipe FAQs

Can I use a different type of pasta in this casserole?

Absolutely! While orzo works wonderfully, feel free to substitute it with your preferred small pasta varieties such as ditalini or even quinoa for a gluten-free version. Just keep an eye on the cooking times, as different pastas may require different amounts of liquid and cooking times.

Is this casserole vegetarian-friendly?

Yes, this Garlic Parmesan Cauliflower Casserole is vegetarian-friendly! The use of vegetable broth and no meat ingredients makes it a delightful option for vegetarians. You can also easily make it vegan by substituting the cream cheese with a plant-based cream cheese variant.

How can I enhance the flavor of this casserole?

For a bolder flavor, consider adding sautéed onions or mushrooms to the mix before baking. You could also fold in some fresh herbs like basil or parsley right before serving for an extra pop of freshness.

What sides pair well with this dish?

This casserole is rich and satisfying, making it a fantastic stand-alone meal. However, if you’re looking to round things out, it pairs beautifully with a light arugula salad or steamed green beans for a well-balanced dinner.
