Step-by-Step Guide to Making Cheesy Green Bean Casserole

Ingredients You’ll Need

For the Casserole:

• 1 pound fresh green beans, trimmed and cut into bite-sized pieces (or a mix of green beans and cauliflower florets)
• 2 tablespoons butter or olive oil
• 1 small onion, finely diced
• 2 cloves garlic, minced
• 1 cup heavy cream
• 1 cup shredded cheddar cheese
• 1/2 cup shredded mozzarella cheese
• 1/4 cup grated Parmesan cheese
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• Salt and pepper, to taste

For the Topping:

• 1 cup crushed pork rinds (or almond flour mixed with melted butter for a homemade crispy topping)
• Optional: 1/4 cup shredded Parmesan cheese for extra crunch

Instructions

1. Preheat the Oven :
   • Preheat your oven to 375°F (190°C). Grease a baking dish.
2. Prepare the Green Beans :
   • Blanch the green beans by boiling them in salted water for 3-4 minutes, then plunging them into ice water to stop the cooking process. Drain and set aside. (Skip this step if using frozen green beans.)
3. Make the Cheese Sauce :
   • In a skillet over medium heat, melt the butter or olive oil. Add the diced onion and cook for 3-5 minutes until softened.
   • Stir in the minced garlic and cook for an additional 30 seconds until fragrant.
   • Reduce the heat to low and stir in the heavy cream, shredded cheddar, mozzarella, and Parmesan cheeses. Cook, stirring constantly, until the cheese melts and the sauce thickens slightly.
   • Season with garlic powder, onion powder, salt, and pepper to taste.
4. Assemble the Casserole :
   • In the prepared baking dish, combine the blanched green beans and cheese sauce. Stir gently to ensure the green beans are evenly coated.
5. Add the Topping :
   • Sprinkle the crushed pork rinds (and optional Parmesan cheese) evenly over the top of the casserole for a crispy finish.
6. Bake Until Golden :
   • Bake for 20-25 minutes, or until the casserole is bubbly and the topping is golden brown.
7. Serve and Enjoy :
   • Let the casserole cool slightly before serving. Pair with your favorite main dish or enjoy as a standalone comfort food.
