For 4 servings
- prep
Preheat the oven and prepare the baking dish.
Preheat your oven to 350°F (175°C). Grease an 8x8-inch baking dish with 1 teaspoon of olive oil and set aside.
- boil · ~4 min
Blanch the vegetables.
1.Bring 6 cups of water to a rolling boil in a large pot. Add 1 teaspoon salt.2.Add broccoli and cauliflower florets to the boiling water and cook for exactly 2 minutes.3.Add the diced carrots and cook for 1 more minute.4.Immediately drain the vegetables into a colander and rinse with cold water to stop the cooking. Spread on a clean kitchen towel to dry.TIPDon't skip the ice-cold rinse — it locks in the bright color and stops the vegetables from turning mushy in the oven. - saute · ~2 min
Start the cheese sauce base.
1.Melt 2 tablespoons butter in a medium saucepan over medium heat.2.Add the minced garlic and sauté until fragrant, about 30 seconds.3.Sprinkle in 2 tablespoons all-purpose flour and whisk continuously for 1 minute to cook out the raw flour taste. - simmer · ~4 min
Finish the creamy cheese sauce.
1.Slowly pour in the warm milk while whisking constantly to avoid lumps.2.Bring the mixture to a gentle simmer and cook for 2 to 3 minutes, stirring often, until it thickens enough to coat the back of a spoon.3.Remove the pan from the heat. Stir in the shredded cheddar cheese, a pinch of salt, black pepper, and paprika until the cheese is fully melted and the sauce is smooth.TIPTake the pan off the heat before adding the cheese — high heat can make the cheddar grainy and separate the sauce. - assemble · ~3 min
Assemble the casserole.
1.Place the blanched, well-drained vegetables into a large mixing bowl.2.Pour the cheese sauce over the vegetables and fold gently until every piece is evenly coated.3.Transfer the mixture into the prepared baking dish and spread it into an even layer.4.Sprinkle the top evenly with the breadcrumbs. - bake · ~30 min
Bake until golden and bubbly.
Place the dish on the middle rack of the preheated oven and bake for 25 to 30 minutes. The casserole is ready when the edges are bubbling and the breadcrumb topping is golden brown.
TIPFor an extra-crispy top, switch the oven to broil for the last 1 to 2 minutes — watch it closely so it doesn't burn. - rest · ~5 min
Let the casserole rest before serving.
Remove from the oven and let the casserole sit for 5 minutes. This helps the sauce set slightly and makes serving easier.
