Method
Step 1: Preheat the Oven
- Start by preheating your oven to 350°F (175°C). This allows the casserole to bake evenly.
Step 2: Prepare the Vegetables
- While the oven warms up, rinse your broccoli and cauliflower thoroughly. Chop them into bite-sized pieces. A good rule of thumb is to keep them roughly the same size so they cook evenly. Set them aside.
Step 3: Make the Sauce
- In a medium saucepan over medium heat, melt the butter. Once it's melted, whisk in the flour until it forms a paste. Gradually add the milk, whisking constantly to avoid lumps. Continue stirring until the mixture thickens – you want a nice creamy texture. This should take about 5 minutes. Once thickened, add the salt, pepper, thyme, sharp cheddar, and Parmesan. Stir until the cheese melts into a smooth sauce. Lastly, mix in the smoked paprika. Your sauce is ready!
- Step 4: Combine the Ingredients
- In a large mixing bowl, combine your chopped broccoli and cauliflower with the minced garlic and diced onions. Pour the cheesy sauce over the vegetables, stirring gently until everything is well-coated.
Step 5: Prepare the Crumb Topping
- In a smaller bowl, mix the breadcrumbs, chopped parsley, melted butter, and garlic powder. This combination will create a golden crust on top of your casserole.
Step 6: Assemble the Casserole
- Transfer the vegetable-sauce mixture into a greased casserole dish. Evenly sprinkle the breadcrumb mixture over the top.
Step 7: Bake the Casserole
- Place the casserole in the preheated oven and bake for about 25 to 30 minutes. You're looking for a golden-brown topping and bubbling cheese.
Step 8: Let It Rest
- Once you take the casserole out, allow it to rest for about 5-10 minutes. This will help it set and make serving easier.
Notes
- Choose Fresh Produce: Aim for fresh broccoli and cauliflower. Frozen can work in a pinch but fresh has a better texture.
- Pre-cook Vegetables: If you want softer veggies, blanch them in boiling water for a couple of minutes before mixing them in.
- Experiment with Cheeses: While sharp cheddar is fantastic, feel free to mix in Gruyère or mozzarella for variety.
- Add Ins: You can include cooked bacon, ham, or even mushrooms for extra flavor. Think about what you like!
- Vegetarian Alternative: You can use vegan substitutes for butter and cheese if you're looking for a plant-based option.
