I remember when green bean casserole used to be a holiday chore, not a joy. But this Green Bean Casserole From Scratch Skillet Bake delivers crispy edges, a creamy, savory center, and that fresh-from-the-garden flavor. It’s a vibrant, hearty side perfect for busy family dinners or your next gathering, transforming a classic into an irresistible, fresh-tasting meal. Even on a Tuesday night, when time is short, this comes together so easily.

Ingredient Spotlight and Why They Matter
- Fresh green beans: 1.5 lbs (680g) fresh green beans, trimmed (for crisp texture and vibrant color).
- Fresh mushrooms: 8 oz (225g) fresh cremini or button mushrooms, sliced (add earthy depth and meaty texture). (Or use leeks for a milder flavor if preferred).
- Homemade or store-bought crispy onions: 1.5 cups (100g) crispy fried onions (for essential crunch and savory topping). (I often use a quality store-bought brand to save time).
- Rich creamy sauce:
- 4 Tbsp (56g) unsalted butter (for richness and roux base).
- 4 Tbsp (30g) all-purpose flour (or 1:1 gluten-free blend) (to thicken the sauce).
- 2 cups (480ml) low-sodium vegetable broth (adds savory liquid).
- 1 cup (240ml) whole milk or half-and-half (or unsweetened plant milk for dairy-free) (for creamy consistency).
- Seasonings: 1 tsp salt, 0.5 tsp black pepper, 1 tsp garlic powder, a tiny pinch of freshly grated nutmeg (these elevate the overall savory taste profile).
Substitutions and Alternatives
- Dairy-free: Use 1 cup (240ml) unsweetened plant-based milk (like almond or oat) and 4 Tbsp (56g) plant-based butter alternatives for a creamy, dairy-free sauce base.
- Gluten-free: Swap 4 Tbsp (30g) all-purpose flour for a 1:1 gluten-free flour blend when making the roux to ensure a smooth, gluten-free sauce.
- Mushroom alternatives: If mushrooms aren’t your favorite, finely diced leeks or shallots (about 1 cup, 120g) sautéed until tender can add a similar savory, aromatic base.
Healthy or Premium Options
- Organic vegetables: Opt for organic green beans and mushrooms to ensure the freshest, highest-quality produce for your Green Bean Casserole From Scratch Skillet Bake.
- Low-sodium broth: Using a low-sodium vegetable broth helps you control the overall sodium content while still delivering great flavor.
- High-protein: For a subtle cheesy flavor and protein boost, stir in 2-3 tablespoons of nutritional yeast to the sauce before combining with the green beans.
Notes on Seasonal Produce or Pantry Staples
- Best fresh: While frozen green beans can work in a pinch, fresh green beans truly make this Green Bean Casserole From Scratch Skillet Bake shine with superior texture and brighter flavor.
- Pantry check: Always ensure you have a quality broth and your preferred milk or cream on hand before starting; these are key to a rich, easy dinner idea.
Easy Cooking Instructions for Green Bean Casserole From Scratch Skillet Bake
- Step 1: Prep your veggies. Trim 1.5 lbs (680g) green beans. Bring a pot of salted water to a boil, add green beans, and cook for 5-7 minutes until tender-crisp and bright green. Drain well and set aside. If they look too soft, they’re overcooked; reduce boiling time next time to keep their snap.
- Step 2: Sauté the aromatics. In a 10-inch oven-safe skillet over medium heat, melt 1 Tbsp butter. Add 8 oz (225g) sliced mushrooms and cook for 5-8 minutes until softened, lightly browned, and fragrant.
- Step 3: Craft the creamy sauce. Add 3 Tbsp (42g) butter to the skillet with the mushrooms. Once melted, whisk in 4 Tbsp (30g) flour for 1 minute, forming a roux that smells toasty. Gradually whisk in 2 cups (480ml) broth, then 1 cup (240ml) milk until the sauce thickens and coats the back of a spoon, about 3-5 minutes. Season with salt, pepper, garlic powder, and nutmeg.
- Step 4: Combine and bake. Stir the pre-cooked green beans into the creamy sauce in the skillet until well coated. Top evenly with 1.5 cups (100g) crispy onions. Bake the Green Bean Casserole From Scratch Skillet Bake at 375°F (190°C) for 20-25 minutes, or until the sauce is bubbling and the onions are golden brown and extra crisp. For a quick weeknight Green Bean Casserole From Scratch Skillet Bake, I’ve even used pre-sliced mushrooms and already crispy onions from the grocery store – it makes a big difference in getting dinner on the table faster.
Inline Variation Notes
- Family style: For an extra rich and indulgent Green Bean Casserole From Scratch Skillet Bake, use heavy cream instead of milk, creating a denser, more luxurious texture for your casserole.
- Lighter/healthier: Opt for skim milk or unsweetened almond milk for a lighter sauce; it still provides creaminess without the added richness, making for a healthier meal.
- Extra crunch: To boost the crispy onion texture, add another half cup (35g) of crispy onions during the last 10 minutes of baking.
Quick Warnings About Common Mistakes
- Don’t overcook green beans: Pre-cook green beans until tender-crisp (they should still have a slight bite) because they will continue to soften in the oven.
- Don’t overcrowd the skillet: Ensure the mushrooms and green beans have enough space to spread out; overcrowding can lead to steaming instead of proper browning and crisping.
- Avoid burning the roux: Cook the flour gently with the butter for only 1-2 minutes until it smells nutty, before adding liquids, to preserve the delicious flavor of this Green Bean Casserole From Scratch Skillet Bake.

Description
This Green Bean Casserole From Scratch Skillet Bake transforms a holiday classic into an irresistible, fresh-tasting meal with crispy edges and a creamy, savory center. It’s a vibrant, hearty side perfect for busy family dinners or gatherings, coming together easily even on a weeknight.
Ingredients
- 1.5 lbs fresh green beans, trimmed
- 8 oz fresh cremini or button mushrooms, sliced
- 1.5 cups crispy fried onions
- 4 Tbsp unsalted butter
- 4 Tbsp all-purpose flour (or 1:1 gluten-free blend)
- 2 cups low-sodium vegetable broth
- 1 cup whole milk or half-and-half (or unsweetened plant milk for dairy-free)
- 1 tsp salt
- 0.5 tsp black pepper
- 1 tsp garlic powder
- a tiny pinch of freshly grated nutmeg
Instructions
- Prep Green Beans: Trim 1.5 lbs (680g) green beans. Bring a pot of salted water to a boil, add green beans, and cook for 5-7 minutes until tender-crisp and bright green. Drain well and set aside.
- Sauté Mushrooms: In a 10-inch oven-safe skillet over medium heat, melt 1 Tbsp butter. Add 8 oz (225g) sliced mushrooms and cook for 5-8 minutes until softened, lightly browned, and fragrant.
- Make Creamy Sauce: Add 3 Tbsp (42g) butter to the skillet with the mushrooms. Once melted, whisk in 4 Tbsp (30g) flour for 1 minute, forming a roux. Gradually whisk in 2 cups (480ml) broth, then 1 cup (240ml) milk until the sauce thickens and coats the back of a spoon, about 3-5 minutes. Season with salt, pepper, garlic powder, and nutmeg.
- Combine And Bake: Stir the pre-cooked green beans into the creamy sauce in the skillet until well coated. Top evenly with 1.5 cups (100g) crispy onions. Bake at 375°F (190°C) for 20-25 minutes, or until the sauce is bubbling and the onions are golden brown and extra crisp.
Notes
For dairy-free, use plant-based milk and butter; for gluten-free, use a 1:1 gluten-free flour blend for the roux. If mushrooms are not preferred, finely diced leeks or shallots (about 1 cup, 120g) can be sautéed instead. Opt for organic vegetables and low-sodium broth for higher quality and controlled sodium. For a protein boost, stir in 2-3 tablespoons of nutritional yeast to the sauce. Fresh green beans offer superior texture and flavor, though frozen can be used. Do not overcook green beans initially, as they will soften further in the oven. Avoid overcrowding the skillet to ensure proper browning of mushrooms. Cook the roux gently for 1-2 minutes to prevent burning. For an extra rich casserole, use heavy cream instead of milk; for a lighter version, use skim milk or unsweetened almond milk. For extra crunch, add another 0.5 cup (35g) of crispy onions during the last 10 minutes of baking.
