Step‑by‑Step Instructions for Homemade Green Bean Casserole
Step 1: Prepare the Shallots
Begin by thinly slicing the shallots to promote even frying. Heat a medium skillet over medium heat and add olive oil. Once the oil shimmers, carefully add the sliced shallots and fry them for about 5-7 minutes, stirring frequently, until they are golden brown and crispy. Remove them from the skillet and set them aside on a paper towel to absorb excess oil.
Step 2: Blanch the Green Beans
In a large pot, bring salted water to a rolling boil. Add fresh or frozen green beans and blanch them for 3-4 minutes, ensuring they remain bright green and tender-crisp. As soon as the time’s up, transfer the beans to a bowl filled with ice water to cool and halt the cooking process. Drain and set aside while you prepare the mushroom sauce.
Step 3: Make the Creamy Mushroom Sauce
In the same skillet used for the shallots, add a bit more olive oil and sauté sliced mushrooms over medium heat for about 5 minutes until they are tender and their moisture has evaporated. Pour in heavy cream and chicken broth, stirring to combine. Season the mixture with thyme, garlic powder, salt, and pepper, and let it simmer for about 8-10 minutes, allowing it to thicken to a velvety consistency.
Step 4: Combine Ingredients
Once the creamy mushroom sauce has thickened, gently fold the blanched green beans into the sauce until they are evenly coated. Carefully transfer this mixture to a greased 9×13-inch baking dish, spreading it evenly across the bottom. This creamy layer is the heart of your Homemade Green Bean Casserole, ready for its delicious topping.
Step 5: Top & Bake
Sprinkle the crispy shallots generously over the green bean and sauce mixture, followed by a layer of freshly grated Parmesan cheese. Preheat your oven to 375°F (190°C) and bake the casserole uncovered for 20 minutes. After this, uncover once more and bake for an additional 7-10 minutes until the top is bubbly and golden brown, creating a beautiful contrast to the creamy filling below.
