• Broccoli florets: 4 cups, fresh or frozen (thawed if frozen), the star vegetable, offering a healthy dose of nutrients and a delightful texture.
• Butter: 1/2 cup (1 stick), unsalted, creates a rich and flavorful base for the sauce.
• All-purpose flour: 1/2 cup, helps thicken the cheese sauce to creamy perfection.
• Milk: 4 cups, whole milk or 2% milk, forms the liquid base of the creamy sauce.
• Sharp cheddar cheese: 4 cups, shredded, the quintessential cheesy flavor that makes this casserole irresistible. Use a good quality cheese for the best taste.
• Monterey Jack cheese: 2 cups, shredded, adds a mild, melty complement to the sharp cheddar and contributes to a gooey texture.
• Onion: 1 medium, finely chopped, provides aromatic base notes to the sauce.
• Garlic: 2 cloves, minced, enhances the savory flavor profile of the dish.
• Dijon mustard: 1 tablespoon, adds a subtle tang and complexity to the cheese sauce.
• Hot sauce: 1/2 teaspoon (optional), for a touch of heat and depth (adjust to taste).
• Salt: 1 teaspoon, or to taste, enhances the overall flavor and balances the cheese.
• Black pepper: 1/2 teaspoon, freshly ground, adds a hint of spice and complements the other flavors.
• Paprika: 1 teaspoon, sweet or smoked, for color and a subtle smoky note (smoked paprika is particularly delicious).
• Bread crumbs: 1 cup, panko or regular, for a crispy topping (optional but highly recommended).
• Parmesan cheese: 1/2 cup, grated, adds a salty, nutty flavor to the topping (optional but enhances the crispiness and flavor).

Step-by-Step Instructions for Making Broccoli Cheddar Vegetarian Rice Casserole

1. Preheat the Oven and Prepare Baking Dish: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish. Properly preheating the oven ensures even cooking and a beautifully golden brown top. Greasing the dish prevents sticking and makes serving easier.
2. Cook the Rice: In a large saucepan, combine the uncooked long-grain rice and vegetable broth. Bring to a boil over high heat, then reduce heat to low, cover, and simmer for 18-20 minutes, or until the rice is tender and the liquid is absorbed. Fluff with a fork and set aside. Cooking the rice separately first ensures it’s perfectly cooked and not mushy in the casserole. Using vegetable broth instead of water adds significant flavor to the rice base.
3. Sauté Aromatics: While the rice is cooking, melt the butter in a large skillet over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes. Then, add the minced garlic and cook for another minute until fragrant, being careful not to burn the garlic. Sautéing the onion and garlic first develops their flavors, creating a richer and more aromatic base for the cheese sauce.
4. Make the Cheese Sauce: Sprinkle the all-purpose flour over the sautéed onions and garlic in the skillet. Cook, stirring constantly, for 1-2 minutes to cook out the raw flour taste and create a roux. Gradually whisk in the milk, a little at a time, ensuring each addition is fully incorporated before adding more. This prevents lumps and creates a smooth sauce. Continue whisking until the sauce thickens slightly and comes to a gentle simmer.
5. Incorporate Cheese and Seasonings: Remove the skillet from the heat. Stir in the shredded sharp cheddar cheese and Monterey Jack cheese, stirring until melted and smooth. Add the Dijon mustard, hot sauce (if using), salt, pepper, and paprika. Taste and adjust seasonings as needed. Adding the cheese off the heat helps prevent it from becoming grainy. Dijon mustard and hot sauce enhance the cheese flavor without making it overly spicy.
6. Combine Ingredients: In a large bowl, gently combine the cooked rice, broccoli florets, and cheese sauce. Stir until everything is evenly coated. Make sure the broccoli is evenly distributed throughout the rice and sauce mixture for a balanced casserole.
7. Transfer to Baking Dish and Top (Optional): Pour the rice and broccoli mixture into the prepared baking dish, spreading it out evenly. If desired, in a small bowl, combine the bread crumbs and grated Parmesan cheese. Sprinkle the bread crumb mixture evenly over the top of the casserole. This creates a delightful crispy topping that contrasts beautifully with the creamy interior.
8. Bake the Casserole: Bake in the preheated oven for 20-25 minutes, or until the casserole is heated through, bubbly around the edges, and the topping is golden brown (if using). Baking until bubbly ensures the casserole is heated all the way through and the cheese is melted and gooey.
9. Rest and Garnish: Let the casserole rest for 5-10 minutes before serving. This allows it to set slightly and makes it easier to serve. Garnish with fresh chopped parsley before serving for a pop of freshness and color.

Additional Tips for the Best Broccoli Cheddar Vegetarian Rice Casserole

1. Use Good Quality Cheese: The quality of cheese significantly impacts the flavor of this casserole. Opt for good quality sharp cheddar and Monterey Jack cheese. Pre-shredded cheese often contains cellulose, which can prevent it from melting as smoothly. Shredding your own cheese is recommended for the best texture and melt.
2. Don’t Overcook the Broccoli: Whether using fresh or frozen broccoli, avoid overcooking it. You want it to be tender-crisp, not mushy. If using fresh broccoli, blanch it briefly in boiling water for 2-3 minutes before adding it to the casserole to ensure it’s tender but still has some bite. If using frozen broccoli, thaw it completely and drain excess water before use.
3. Customize the Cheese: Feel free to experiment with different cheese combinations. Gruyere, fontina, or pepper jack can be delicious additions or substitutions for Monterey Jack. For a smokier flavor, try using smoked Gouda or smoked cheddar.
4. Add More Vegetables: Want to boost the nutritional value and flavor? Consider adding other vegetables like sautéed mushrooms, chopped carrots, cauliflower florets, or peas to the casserole. Sauté mushrooms and carrots along with the onion and garlic. Peas can be added directly to the casserole mixture before baking.
5. Make it Gluten-Free: To make this casserole gluten-free, use gluten-free all-purpose flour blend for the sauce and ensure your bread crumbs (if using) are also gluten-free. Rice is naturally gluten-free, so the base is already compliant.
6. Prepare Ahead of Time: You can assemble the casserole ahead of time and store it, unbaked, in the refrigerator for up to 24 hours. When ready to bake, add about 10-15 minutes to the baking time to ensure it’s heated through. This is perfect for meal prepping or when you have guests coming over.
7. Spice it Up: If you enjoy a bit more heat, increase the amount of hot sauce or add a pinch of red pepper flakes to the cheese sauce. You could also use pepper jack cheese for a spicy kick.
8. Crispy Topping Variations: For a different crispy topping, try using crushed crackers (like Ritz crackers or gluten-free crackers), fried onions, or even potato chips instead of bread crumbs. These variations add different textures and flavors to the casserole topping.

Frequently Asked Questions About Broccoli Cheddar Vegetarian Rice Casserole (FAQ)

Q1: Can I use brown rice instead of white rice?
A: Yes, you can use brown rice, but keep in mind that brown rice takes longer to cook than white rice. You’ll need to adjust the cooking time accordingly. Brown rice will also result in a slightly denser and nuttier casserole compared to using white rice. Ensure the brown rice is fully cooked before adding it to the casserole mixture.

Q2: Can I use frozen broccoli without thawing it first?
A: It’s best to thaw frozen broccoli before adding it to the casserole. Frozen broccoli contains a lot of water, and adding it frozen can make the casserole watery. Thawing and draining excess water will prevent this and ensure the casserole has the right consistency.

Q3: Can I make this casserole dairy-free or vegan?
A: Yes, with substitutions! To make it dairy-free, use plant-based butter, unsweetened plant-based milk (like almond, soy, or oat milk), and dairy-free cheddar and Monterey Jack style shreds. For a vegan version, ensure your cheese shreds are vegan-certified and consider using nutritional yeast for an extra cheesy flavor boost in the sauce.

Q4: How do I store leftover broccoli cheddar rice casserole?
A: Store leftover casserole in an airtight container in the refrigerator for up to 3-4 days. Reheat it in the oven at 350°F (175°C) until heated through, or microwave individual portions for quicker reheating. You may need to add a splash of milk or broth when reheating to restore some moisture.

Q5: Can I freeze broccoli cheddar rice casserole?
A: Yes, you can freeze this casserole. Let it cool completely, then wrap it tightly in plastic wrap and then aluminum foil, or store it in a freezer-safe container. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating in the oven. The texture of the sauce might change slightly after freezing and thawing, but it will still be delicious.

Q6: What can I serve with broccoli cheddar rice casserole to make it a complete meal?
A: A simple green salad or a side of roasted vegetables like asparagus, Brussels sprouts, or green beans would make a great accompaniment. A light and fresh side dish will balance the richness of the casserole. You can also serve it with a protein like grilled chicken or fish if you’re not strictly vegetarian, although it’s satisfying enough on its own.

Q7: My cheese sauce is lumpy. How can I fix it?
A: Lumpy cheese sauce can often be fixed. If it’s only slightly lumpy, try whisking it vigorously over low heat. If it’s very lumpy, you can strain the sauce through a fine-mesh sieve to remove the lumps. To prevent lumps in the future, make sure to whisk the flour into the melted butter thoroughly to create a smooth roux before adding the milk, and gradually add the milk while whisking constantly.

Q8: Can I make this casserole in a slow cooker?
A: While you can adapt this recipe for a slow cooker, baking in the oven is generally recommended for the best texture, especially for the crispy topping. If you want to use a slow cooker, cook the rice and make the cheese sauce separately. Then, combine the cooked rice, broccoli, and cheese sauce in the slow cooker. Cook on low for 2-3 hours, or until heated through. The topping won’t get as crispy in the slow cooker. You could consider broiling the top briefly in the oven after slow cooking to crisp it up if desired.
