Step-by-Step Instructions for Making French Onion Broccoli Cheese Casserole
Making French onion broccoli cheese casserole is simple with this clear guide. Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish. Warm olive oil and 2 tablespoons butter in a skillet over medium-low heat. Add onions, sugar, and ½ teaspoon salt. Cook for 20–25 minutes, stirring occasionally, until golden and jammy. Stir in garlic and thyme for 1 minute. Remove from heat. Blanch broccoli florets in boiling salted water for 2 minutes until bright green and crisp-tender. Drain well and pat dry. Melt 2 tablespoons butter in a saucepan over medium heat. Whisk in flour and cook for 1 minute. Slowly whisk in beef broth and milk, simmering until thickened (3–4 minutes). Off heat, stir in Gruyère and half of the cheddar until smooth. Season with remaining salt and black pepper. In the prepared dish, combine broccoli, caramelized onions, and cheese sauce.
