Save

For the Creamy Mushroom Sauce:

• 1 lb crimini mushrooms, thinly sliced
• 4 tbsp unsalted butter
• 1 large shallot, minced
• 2 cloves garlic, minced
• 1/2 cup heavy cream
• 1/2 cup chicken or vegetable broth
• 1/4 cup dry white wine (like a Sauvignon Blanc, IMO)
• 2 tbsp all-purpose flour
• 1/2 tsp dried thyme
• Salt and black pepper to taste

For the Green Beans:

• 2 lbs fresh green beans, trimmed and blanched
• 1/4 cup water

For the Crispy Onions:

• 1 large yellow onion, thinly sliced into rings
• 1/4 cup all-purpose flour
• 1/4 tsp salt

Substitutions? Yes, you can!

• Mushrooms: Can’t find crimini? White button mushrooms work just fine.
• Heavy Cream: Want a lighter sauce? You can use half-and-half, but the sauce won’t be as rich.
• Green Beans: No fresh beans? Use frozen, but thaw and dry them well before adding to the casserole. Canned beans are a no-go, FYI.
• Crispy Onions: In a pinch, you can use store-bought French fried onions, but TBH, the homemade ones are a game changer.

Let’s Get Cooking! Your Step-by-Step Guide to Perfection

Ready to become the casserole master? Let’s dive in.

Step 1: Blanch the Green Beans

1. Bring a large pot of salted water to a rolling boil.
2. Add the trimmed green beans and cook for 3-4 minutes. They should be vibrant green and slightly tender, but still have a good snap.
3. Immediately drain the beans and plunge them into a bowl of ice water. This stops them from cooking further and preserves their color. Drain again and set them aside.

Step 2: Make the Crispy Onions

1. Pour enough vegetable oil into a large pot to reach about 2 inches deep. Heat the oil to 350°F (175°C).
2. In a medium bowl, toss the thinly sliced onion rings with the flour, salt, and paprika. Make sure every ring is lightly coated.
3. Working in batches, fry the onions for 2-3 minutes, or until they are a beautiful golden brown and crispy. Don’t crowd the pot!
4. Remove the onions with a slotted spoon and transfer them to a paper towel-lined plate to drain. Sprinkle with a little extra salt while they’re still hot.

Step 3: Create the Creamy Mushroom Sauce

1. Melt the butter in a large skillet or Dutch oven over medium-high heat.
2. Add the sliced mushrooms and cook, stirring occasionally, until they are browned and have released their liquid, about 8-10 minutes.
3. Add the shallot and garlic to the skillet and cook for another minute until fragrant.
4. Stir in the flour and cook for one minute, stirring constantly. This creates your roux.
5. Slowly pour in the white wine, whisking constantly to scrape up any browned bits from the bottom of the pan. Cook for one minute.
6. Gradually whisk in the broth and heavy cream. Bring the sauce to a gentle simmer, whisking frequently, until it thickens.
7. Stir in the dried thyme and season with salt and pepper. Taste and adjust seasonings as needed. This sauce is your new best friend.

Step 4: Assemble and Bake

1. Preheat your oven to 375°F (190°C).
2. Add the blanched green beans to the skillet with the sauce. Stir gently to coat every bean.
3. Pour the mixture into a 9×13 inch baking dish. Top with a generous handful of the homemade crispy onions.
4. Bake for 20-25 minutes, or until the casserole is hot and bubbly.
5. Remove from the oven and top with the remaining crispy onions right before serving. This is crucial for maximum crunch!

• Fiber: Good source from the green beans and mushrooms.

Common Mistakes to Avoid (You’re Welcome)

Steer clear of these common pitfalls and you’re golden!

• Mushrooms that Don’t Brown: Don’t overcrowd the pan with your mushrooms. Cook them in batches if you need to, or they’ll steam instead of brown. Golden-brown mushrooms equal deep flavor.
• Soggy Green Beans: Don’t skip the blanching and shocking steps! This ensures your green beans have that perfect, crisp-tender texture.
• Lumpy Sauce: The key to a smooth sauce is to whisk constantly as you add the liquid. If it does get lumpy, don’t fret; a quick whiz with an immersion blender will fix it right up.
• Soft Onions: Don’t put all the onions on top before baking. They’ll just get soggy. Save the majority of the crispy onions to put on at the end for that glorious crunch.

Variations & Customizations: Get Creative!

Want to get a little wild? Here are some fun ways to mix it up.

• Bacon-Lover’s Delight: Cook diced bacon with the shallots and mushrooms. Use the rendered bacon fat instead of some of the butter for extra smoky flavor.
• Keto-Friendly: Swap out the all-purpose flour for almond flour in the sauce, and make the crispy onion topping with pork rinds or just use chopped pecans and bacon instead.
• Spicy Kick: Add a pinch of red pepper flakes to the sauce with the garlic, or stir in a teaspoon of your favorite hot sauce.

FAQ Section: Your Burning Questions Answered

We know you have questions, and we’ve got answers!

Q1: Can I make green bean casserole ahead of time?

A: You can assemble the casserole a day in advance (without the crispy onions). Cover it and refrigerate. Let it come to room temperature for 30 minutes before baking, then add the onions and bake as directed.

Q2: What’s the best way to store leftovers?

A: Store leftovers in an airtight container in the refrigerator for up to 3-4 days. The onions won’t be as crispy, but it will still taste amazing.

Q3: Can I freeze green bean casserole?

A: Yes, you can! You can freeze it before or after baking. If freezing before, assemble the casserole (without the onions) and wrap it tightly. Freeze for up to 3 months. Thaw overnight in the fridge and then bake.

Q4: Why are my green beans tough?

A: You probably didn’t blanch them long enough. They should be slightly tender before they go into the casserole, since they won’t cook much more in the oven.

Q5: Can I use fresh mushrooms instead of canned?

A: Yes! In fact, this recipe is designed for fresh mushrooms because they provide so much more flavor and texture.

Q6: How do I get my sauce to thicken?

A: The combination of butter and flour creates a roux, which thickens the sauce. Make sure you whisk constantly while adding the liquid. If it’s still too thin, you can make a slurry of cornstarch and water and whisk it in a little at a time until you reach your desired consistency.

Q7: Can I use different types of onions for the topping?

A: Absolutely. Sweet onions like Vidalia work great and will caramelize beautifully. Red onions can add a nice color and a slightly sharper flavor.
