How to make Gluten-Free Fried Onions for Green Bean Casserole
Gluten-free fried onions for green bean casserole are crispy onion toppings made without wheat or gluten-containing ingredients, designed to replace the traditional French’s fried onions often used on top of the classic holiday dish.
Ingredients
- 2 large yellow or white onions – Thinly sliced into rings or strips.
- ½ cup gluten-free all-purpose flour – Look for a high-quality blend like Bob’s Red Mill or King Arthur.
- ¼ cup cornstarch – Helps create an ultra-crispy coating.
- 1 teaspoon salt – For flavor.
- ½ teaspoon garlic powder (optional) – To enhance the savory taste.
- Freshly ground black pepper – Adjust to taste.
- Vegetable or neutral oil for frying – Canola, avocado, or sunflower oil work well.
- Optional: Paprika or cayenne for a hint of spice (use sparingly).
Instructions
- Prep the Onions: Peel the onions and slice them into thin rings or strips (around ¼-inch thick). Separate the slices so they’re not clumped together.
- Make the Coating: In a large mixing bowl, combine your gluten-free flour, cornstarch, salt, garlic powder (if using), and black pepper. Whisk everything together to ensure even seasoning.
- Coat the Onions: Toss the onion slices in the gluten-free flour mix, making sure each piece is well-coated. For extra crispiness, press the onion strips gently into the flour mixture to ensure the coating sticks nicely.
- Heat the Oil: Add about 1–2 inches of oil to a deep frying pan or pot and heat it over medium-high heat. The oil should reach roughly 350°F (175°C). If you don’t have a thermometer, test by dropping a small bit of coated onion into the oil—if it sizzles immediately, it’s ready.
- Fry the Onions: Work in small batches to avoid overcrowding the pan. Carefully add the coated onion slices to the hot oil and fry them for 1–2 minutes per side, or until golden brown and crispy. Use a slotted spoon to transfer the fried onions to a plate lined with paper towels or a cooling rack to drain excess oil.
- Cool and Store: Let the Gluten-Free Fried Onions for Green Bean Casserole cool completely. Once cooled, they become even crispier! Use them immediately or store in an airtight container for up to 1 day.
Tips for Perfect Gluten-Free Fried Onions
- Slice Evenly: Evenly sliced onions ensure they cook uniformly. Use a mandoline slicer for precise and thin slices.
- Choose the Right Oil: A neutral oil with a high smoke point, like canola or avocado oil, is ideal for frying. This prevents unwanted flavors and burned onions.
- Don’t Skip Cornstarch: Cornstarch is key to achieving that light, crispy texture. If you don’t have cornstarch, potato starch works as an alternative.
- Fry in Batches: Overcrowding the pan lowers the oil temperature, resulting in soggy onions. Fry small batches for optimal crispiness.
- Season Generously: Add extra garlic powder, smoked paprika, or cayenne to the flour mixture for customized flavor.
- Cooling is Key: Fried foods need to cool slightly to crisp up. Resist the urge to skip this step!
Ingredients Substitutes
Cooking for special diets doesn’t have to be stressful or complicated. If you’re missing an ingredient or want alternative options while making Gluten-Free Fried Onions for your Green Bean Casserole, here are some clever substitutions to customize the recipe while keeping it gluten-free and delicious!
1. Onions
Substitutes:
Not a fan of traditional white or yellow onions? Here are some alternative options:
- Red Onions: For a sweeter, milder flavor and colorful presentation.
- Shallots: Perfect for a gourmet twist; they fry up super crispy and have a delicate, refined flavor.
- Leeks: Thin slices of leek can provide an interesting texture and flavor, though they’re less sweet than onions.
- Store-Bought Gluten-Free Fried Onion Brands: If you’re short on time, look for options like Crunchsters fried onions or other ready-made gluten-free brands for convenience.
2. Gluten-Free Flour
Substitutes:
A critical ingredient for creating a crispy coating, gluten-free flour can easily be swapped depending on your preferences or pantry supply:
- Rice Flour: Light and crisp; perfect for frying.
- Potato Starch: Great for extra crunch.
- Tapioca Flour: Adds a slightly chewy texture but still crisps up nicely.
- Chickpea Flour (Besan): Nutty and hearty, though slightly heavier than rice flour.
- Almond Flour: Works, but can brown faster due to its natural oil content.
- Gluten-Free Pancake Mix: Surprisingly effective, as long as it’s unsweetened.
3. Cornstarch
Substitutes:
Cornstarch is essential for creating that light and crispy texture, but here are several alternatives:
- Arrowroot Powder: Works identically to cornstarch for frying and crisping.
- Potato Starch: A fantastic replacement, providing that airy crunch.
- Gluten-Free Breadcrumbs: Crush them finely and use them as part of the coating mix for extra flavor and texture.
- Flour (any listed above): You can use gluten-free flour exclusively, though combining it with starch yields the crispiest onions.
4. Oil
Substitutes:
Frying requires oil with a high smoke point—these alternatives will work equally well:
- Avocado Oil: Neutral taste and a high smoke point.
- Canola Oil: Affordable and widely available for frying.
- Sunflower Oil: Great for frying and doesn’t overpower the onion flavor.
- Grapeseed Oil: Light with a mild flavor.
- Peanut Oil: Adds richness but be cautious if you’re serving guests with nut allergies!
5. Seasonings
Substitutes:
Customize the seasoning mix for your fried onions to suit your taste—you can explore these options:
- Salt Alternatives: Use garlic salt, onion salt, or seasoning salts like Lawry’s for more flavor depth.
- Black Pepper Substitutes: White pepper provides a milder, slightly tangy heat.
- Savory Boosters: Smoked paprika, cayenne, or chili powder for spicier fried onions.
- Dried Herbs: Add a pinch of parsley, rosemary, or thyme to the coating for a pop of herbaceous flavor.
