Kristi’s Gluten-Free Green Bean Casserole

My grandma, bless her heart, used to make a green bean casserole every Thanksgiving, and while I loved her dearly, that casserole was… well, let’s just say it was very “canned soup” forward. The gelatinous sauce and soggy fried onions were a yearly tradition I endured for family harmony. So, when I decided to tackle a green bean casserole myself, I knew I wanted something fresh, vibrant, and definitely gluten-free. This recipe is my ode to tradition, reimagined for a modern palate, and guaranteed to make even the most skeptical green bean casserole critic a convert.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 40 minutes
• Total Time: 1 hour 10 minutes
• Servings: 6
• Yield: 1 casserole
• Dietary Type: Gluten-Free

Ingredients

For the Sauce:

• ¼ cup butter
• ¼ cup rice flour
• 1 teaspoon garlic powder
• 2 teaspoons fresh coarse ground black pepper
• 1 teaspoon dry mustard
• 1 teaspoon paprika
• 2 ½ cups milk
• 1 ¾ cups Monterey Jack cheese, divided
• 1 medium onion, quartered and sliced
• ¾ cup button mushroom, halved and sliced
• 2 small jalapenos, halved, seeded, and sliced
• Oil (for frying)

For the Casserole:

• 1 lb fresh green beans, cleaned and snapped
• ¾ cup green onion, chopped

Equipment Needed

• Medium saucepan
• Cast iron pan (or other heavy-bottomed skillet)
• Apparatus for draining fried foods (paper towels, wire rack)
• 8×8 inch baking dish or small casserole dish

Instructions

1. First, let’s get started on that creamy, flavorful sauce. Melt ¼ cup of butter in a medium saucepan over medium heat.
2. Whisk in ¼ cup rice flour, 1 teaspoon garlic powder, 2 teaspoons black pepper, 1 teaspoon dry mustard, and 1 teaspoon paprika. Cook, stirring constantly, until the mixture is lightly browned and begins to pull away from the sides of the pan – this usually takes about 2-3 minutes.
3. Gradually add 2 ½ cups milk, whisking constantly to prevent lumps from forming. Continue stirring until the sauce thickens to a pourable consistency. If it becomes too thick, add a splash more milk to thin it out. Reduce heat to low and keep the sauce warm, stirring occasionally to prevent clumping.
4. Now, for the crispy fried elements. In a cast iron pan (or other heavy-bottomed skillet), heat about ¼ inch of oil over medium-high heat.
5. Add the ¾ cup mushroom halves to the hot oil and fry for about 5 minutes, or until they are golden brown and you can smell that irresistible mushroomy aroma. Remove the mushrooms from the pan and drain on paper towels or a wire rack. Be sure to reserve the oil in the pan, as we’ll be using it for the onions and jalapenos.
6. Add the drained mushrooms and about ¾ cup of the Monterey Jack cheese (reserving the remaining cup) to the sauce. Stir over low heat until the cheese is fully melted and incorporated into the sauce. Set aside.
7. Add the quartered and sliced onions to the hot oil in batches. Don’t overcrowd the pan, or the onions will steam instead of fry. Fry for 4-5 minutes per batch, or until golden brown and crispy. Remove to your draining apparatus and allow to drain thoroughly.
8. Repeat the frying process with the sliced jalapenos (they should be able to be done in one batch). Fry until they are blistered and slightly softened. Remove and drain alongside the onions.
9. Preheat your oven to 325°F (160°C).
10. While you’re waiting for those onions and jalapenos to finish frying, get out your 1 lb of cleaned and snapped fresh green beans. If you’re using frozen, ensure they are very well drained and thawed!
11. Arrange the green beans in an 8×8 inch baking dish or other small casserole dish.
12. Pour about 1 cup of the cheese sauce over the green beans. Add more if you like it extra cheesy! Mix it in as best you can; it won’t be perfect.
13. On top of the green bean and sauce mixture, scatter ½ to 1 cup of the remaining Monterey Jack cheese.
14. Scatter the drained fried onions, jalapenos, and ¾ cup chopped green onions evenly over the top of the casserole.
15. Place the casserole in the preheated oven and bake for approximately 40 minutes, or until the green beans are tender and the cheese is melted and bubbly.
16. Remove from the oven and let rest for 15-20 minutes before serving.

Expert Tips & Tricks

• For extra crispy fried onions: Toss the sliced onions in a bit of rice flour before frying. This will help them crisp up beautifully and prevent them from becoming soggy.
• Make-ahead tip: The sauce can be made up to 2 days in advance and stored in the refrigerator. Reheat gently before assembling the casserole. You can also fry the onions and jalapenos a day ahead and store them in an airtight container at room temperature.
• Spice it up: For an extra kick, add a pinch of cayenne pepper to the sauce or use a spicier variety of jalapeno.
• Cheese Variations: Feel free to experiment with different cheeses. Sharp cheddar, Gruyere, or even a smoked Gouda would be delicious additions.
• Bacon Boost: Fry up some crispy bacon and crumble it over the top of the casserole before baking for a smoky, savory twist. You can even use the bacon fat to make the sauce for an even richer flavor.

Serving & Storage Suggestions

Serve Kristi’s Gluten-Free Green Bean Casserole warm as a side dish. It’s the perfect accompaniment to roast chicken, turkey, or a vegetarian main course.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover the casserole with foil and bake in a preheated oven at 350°F (175°C) until heated through. You can also reheat individual portions in the microwave. Freezing is not recommended as the texture of the sauce may change.

FAQs (Frequently Asked Questions)
