Recipe Ingredients
- Cheddar Cheese: Provides a rich, sharp taste and creamy texture, making the casserole irresistibly cheesy.
- Greek Yogurt: Offers a tangy taste and creamy consistency.
- Paprika: Provides a mild, smoky flavor and vibrant color to the casserole.
See the recipe card for full information on ingredients and quantities.
Variations
- Greek Yogurt Substitute: If you don’t want to use Greek yogurt, you can use light sour cream. It offers a similar tangy flavor and creamy texture.
- Breadcrumb Flexibility: Use whatever breadcrumbs you have. I once used a leftover loaf of challah. I cut it up, toasted it, and gave it a whirl in my food processor. Moral of the story—use what you have on hand!
How to Make Healthy Broccoli Casserole
Step 1: Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius). Lightly butter a 9×13-inch baking dish; set aside.
Step 2: Steam broccoli for a few minutes (do not fully cook the broccoli). Place the broccoli in a large mixing bowl; set aside.
Step 3: In a medium saucepan set over medium heat, add the olive oil. Add the mushrooms and brown, about 6-7 minutes, stirring occasionally. Add the onion and garlic and cook until translucent and fragrant. Transfer to the bowl with the broccoli.
Step 4: In the same saucepan, melt 2 tablespoons of the butter. Whisk in the flour and cook for 1 minute.
Step 5: Slowly whisk in the milk and half-and-half until smooth. Bring the mixture to a low simmer, and whisk until thick. Remove from the heat and whisk in the salt, pepper, paprika, cayenne pepper, and Greek yogurt.
Step 6: Pour sauce into the large mixing bowl (with the veggies). Add the egg, 1 cup of the cheddar cheese, and ½ cup of the breadcrumbs, and mix until combined. Pour into the prepared baking dish.
Step 7: In a medium microwave-safe mixing bowl, melt the remaining tablespoon of butter. Toss the remaining breadcrumbs in and stir to combine, then mix in the remaining cheese. Sprinkle evenly over the broccoli mixture.
Step 8: Place in the oven and bake for 30-40 minutes or until it bubbles and browns (place a piece of foil over the top to prevent over-browning at the 30-minute mark). Remove from the oven and let stand for 10 minutes before serving.
FAQs
Yes, you can use either fresh or frozen broccoli. However, if using fresh broccoli, ensure it is vibrant and firm. Avoid broccoli that looks yellow and becomes limp, as it shouldn’t be consumed.
Whole milk is recommended for its richness, but you can use 2% milk for a lighter option while still achieving a creamy texture.
