Ingredients

• 2 cups broccoli florets, chopped
• 2 cups cauliflower florets, chopped
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1 cup sliced mushrooms
• 1 cup cooked quinoa or rice
• 2 cups shredded cheddar cheese (or a cheese blend)
• 1 cup ricotta cheese
• 1/2 cup grated Parmesan cheese
• 1 cup milk (whole or plant-based)
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 1 teaspoon dried thyme
• Salt and pepper to taste
• 1/2 cup breadcrumbs (optional, for topping)
• 2 tablespoons olive oil

Equipment

• Large skillet for sautéing vegetables
• Medium saucepan for making cheese sauce
• 9×13-inch casserole dish
• Mixing bowls
• Wooden spoon or spatula
• Measuring cups and spoons
• Cheese grater
• Oven mitts

Instructions

1. Preheat your oven to 375°F (190°C) and lightly grease the casserole dish with olive oil or butter.
2. Prepare the vegetables: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until translucent.
3. Add the garlic and mushrooms to the skillet and cook for another 5 minutes until the mushrooms release their moisture and begin to brown.
4. Steam the broccoli and cauliflower florets until just tender (about 5 minutes). Drain and set aside.
5. Make the cheese sauce: In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes until it forms a paste (roux).
6. Gradually whisk in the milk, continuing to stir until the sauce thickens (about 5-7 minutes). Remove from heat and stir in 1 ½ cups of shredded cheddar cheese, ricotta cheese, thyme, salt, and pepper until smooth.
7. Combine all ingredients: In a large bowl, mix the sautéed onion, garlic, mushrooms, steamed broccoli, cauliflower, cooked quinoa, and cheese sauce. Stir gently until everything is well incorporated.
8. Pour the mixture into the prepared casserole dish and smooth the top with a spatula.
9. Top with remaining cheddar cheese, Parmesan cheese, and breadcrumbs for a crunchy, golden finish.
10. Bake uncovered for 25-30 minutes, or until the top is bubbly and golden brown.
11. Remove from oven and let it cool for 5 minutes before serving.

Tips & Variations

Pro Tip: To get an extra crispy topping, broil the casserole for the last 2-3 minutes—but watch closely to avoid burning!

Feel free to swap out the vegetables based on your preferences or seasonal availability. Zucchini, spinach, or bell peppers all make excellent substitutes.

For a different flavor profile, try mixing in some sun-dried tomatoes or olives.

If you want to add a smoky depth, a dash of smoked paprika or a few drops of liquid smoke work beautifully.

For a vegan version, replace dairy cheese with plant-based cheese alternatives and use a non-dairy milk like almond or oat milk.

If you’re hosting a dinner party, consider complementing this dish with a vibrant soup like a classic tomato bisque or a chilled cucumber yogurt soup.
