Ingredients:
- 1 lb fresh green beans, trimmed and cut into bite-sized pieces
- 1 medium head of cauliflower, cut into small florets
- 2 tablespoons butter
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 2 tablespoons all-purpose flour
- 1 1/2 cups milk
- 1/2 cup sour cream
- 1 teaspoon Dijon mustard
- 1 cup shredded cheddar cheese
- 1/4 cup grated Parmesan cheese
- Salt and pepper to taste
- 1/2 cup breadcrumbs
- 2 tablespoons melted butter
- Fresh parsley, chopped (for garnish)
Instructions:
- Preheat the Oven:
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and set aside.
- Cook the Vegetables:
- Bring a large pot of salted water to a boil. Add the green beans and cauliflower florets and cook for 5-7 minutes until just tender. Drain and transfer to the prepared baking dish.
- Prepare the Sauce:
- In a medium saucepan, melt the butter over medium heat. Add the chopped onion and cook until softened, about 5 minutes.
- Stir in the minced garlic and cook for another minute.
- Sprinkle the flour over the onion mixture and stir to combine, cooking for 1-2 minutes to remove the raw flour taste.
- Gradually whisk in the milk, ensuring there are no lumps. Continue to cook, stirring constantly, until the sauce thickens, about 3-5 minutes.
- Add Cheese and Seasoning:
- Remove the saucepan from the heat and stir in the sour cream, Dijon mustard, cheddar cheese, and Parmesan cheese until the cheese is fully melted and the sauce is smooth. Season with salt and pepper to taste.
- Assemble the Casserole:
- Pour the cheese sauce over the green beans and cauliflower in the baking dish, tossing to coat the vegetables evenly.
- Add Topping:
- In a small bowl, mix the breadcrumbs with the melted butter. Sprinkle the breadcrumb mixture evenly over the casserole.
- Bake:
- Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden brown and the sauce is bubbling.
- Serve:
- Garnish with freshly chopped parsley before serving.
Enjoy your Green Bean and Cauliflower Casserole, a delightful and wholesome side dish that pairs perfectly with any meal!
