Ingredients You’ll Need
For about 6 to 8 servings, you’ll need:
- 2 large yellow onions, finely chopped
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon paprika
- 1 large egg
- ¾ cup milk
- 2 tablespoons melted butter
- Vegetable oil, for frying
Yellow onions work especially well because they become sweet and flavorful as they cook. Make sure they are chopped fairly finely so the patties hold together easily.
How to Make Crispy Onion Patties
Step 1: Chop the Onions
Begin by peeling the onions and chopping them very finely.
Place the chopped onions in a large mixing bowl.
The size of your onion pieces matters. If they’re too large, the patties may be difficult to shape and can fall apart during frying. Smaller pieces distribute throughout the batter and make the patties easier to flatten.
If your onions release a lot of liquid after chopping, you don’t need to squeeze them completely dry. Some moisture helps bring the mixture together.
Step 2: Mix the Dry Ingredients
Add the flour, baking powder, salt, black pepper, garlic powder, and paprika directly to the onions.
Stir everything together until the onions are evenly coated with the flour mixture.
The combination of garlic powder, paprika, and black pepper gives these simple patties a savory flavor without overpowering the natural sweetness of the onions.
Step 3: Prepare the Wet Ingredients
In a separate bowl, whisk together the egg, milk, and melted butter.
Make sure the melted butter isn’t extremely hot when you add it to the egg. Warm or slightly cooled melted butter is best.
Whisk until the mixture is smooth and evenly combined.
Step 4: Combine Everything
Pour the wet mixture into the bowl containing the onions and dry ingredients.
Stir everything together until a thick mixture forms.
The batter should be moist but thick enough to hold together when you scoop it into the skillet.
If the mixture seems too thin, let it sit for a minute or two. The flour may absorb some of the liquid and naturally thicken it.
If it still seems too loose, add a small amount of flour, one tablespoon at a time. Avoid adding too much because you want the finished patties to remain tender rather than dense.
Step 5: Heat the Oil
Pour approximately ¼ inch of vegetable oil into a large skillet.
Heat the oil over medium heat.
You want the oil hot enough to create an immediate sizzle when the batter touches it, but not so hot that the outside browns before the center has cooked.
A small drop of batter can be used to test the oil. If it begins sizzling immediately and gradually turns golden, the oil should be ready.
Step 6: Form and Fry the Patties
Using a heaping spoonful of the onion mixture, carefully drop it into the hot oil.
Use the back of the spoon to gently flatten the mixture into a small patty.
Depending on the size of your skillet, you can cook several patties at once. Just make sure you don’t overcrowd the pan.
Fry for approximately 3 to 4 minutes on the first side, or until the bottom is golden brown and crisp.
Carefully flip each patty and cook the other side for another 3 to 4 minutes.
The patties should be deeply golden on both sides and cooked through in the center.
Step 7: Drain and Serve
Transfer the cooked onion patties to a plate lined with paper towels.
Let them sit for a minute or two to absorb excess oil.
Serve them while they’re hot and crispy.
Tips for Perfect Onion Patties
Chop the Onions Finely
Large chunks of onion can make the patties difficult to hold together. Finely chopped onions create a more cohesive mixture and help the patties cook evenly.
Don’t Make the Patties Too Thick
A moderately thin patty gives you the best contrast between a crisp exterior and tender center.
If the patties are too thick, the outside may brown before the middle has cooked.
Keep the Oil at Medium Heat
Oil temperature makes a big difference.
If the oil is too cool, the patties can absorb too much oil and become greasy. If it’s too hot, they can brown too quickly while remaining undercooked inside.
Medium heat is a good starting point, but adjust as needed while cooking.
Don’t Overcrowd the Skillet
Leave some space between the patties. Overcrowding lowers the oil temperature and makes it harder to flip the patties without breaking them.
Cook in batches if necessary.
Let the Batter Rest Briefly
Allowing the mixture to rest for a couple of minutes can help the flour absorb some of the moisture from the onions and milk.
This can make the mixture easier to scoop and shape.
Common Mistakes to Avoid
Using large pieces of onion: They can make the patties fall apart. Chop the onions finely.
Making the batter too thin: The mixture should be thick enough to hold its shape when spooned into the pan.
Using extremely high heat: High heat can burn the outside before the inside is cooked.
Flipping too early: Allow the first side to become golden and firm before attempting to turn the patty.
Overcrowding the pan: Too many patties at once can lower the oil temperature.
Making oversized patties: Smaller patties are easier to cook evenly and flip without breaking.
Easy Variations
These basic onion patties are delicious as written, but they’re also easy to customize.
For a little heat, add a pinch of cayenne pepper or red pepper flakes to the dry ingredients.
Fresh herbs can add a completely different flavor. Try chopped parsley, green onions, chives, or cilantro.
For a cheesy version, mix a small amount of shredded cheddar or Parmesan into the batter.
You can also experiment with the spices. A little cumin, smoked paprika, or dried oregano can give the patties a different personality.
If you enjoy extra crispy edges, make the patties slightly thinner and avoid adding too much batter to the skillet.
What to Serve With Onion Patties
These crispy patties are incredibly versatile.
Serve them alongside:
- Grilled chicken
- Roasted beef
- Burgers
- Sandwiches
- Fried or roasted potatoes
- Fresh green salad
- Grilled vegetables
- Soup or stew
They’re also delicious as a snack with a dipping sauce.
Try serving them with sour cream, ranch-style dressing, garlic sauce, or a simple yogurt and herb dip.
How to Store Leftovers
These onion patties are best when eaten fresh because that’s when they’re at their crispiest.
If you have leftovers, allow them to cool completely and store them in an airtight container in the refrigerator.
To bring back some of their crispiness, reheat them in a skillet or air fryer rather than microwaving them. A microwave will warm them quickly but can make the exterior soft.
When reheating in a skillet, use medium heat and warm the patties on both sides until heated through.
Frequently Asked Questions
Can I make onion patties ahead of time?
Yes. You can prepare the mixture ahead of time and refrigerate it for a short period before frying. For the crispiest results, however, frying them shortly before serving is best.
Why are my onion patties falling apart?
The mixture may be too wet, or the patties may be too large. Add a little more flour if necessary and make smaller patties. Also, allow the first side to cook until firm before flipping.
Can I use another type of onion?
Absolutely. Yellow onions are recommended because of their balanced flavor, but white onions or sweet onions can also work.
How do I make them extra crispy?
Make the patties relatively thin, avoid overcrowding the skillet, and make sure the oil is properly heated before adding the mixture.
Can I freeze onion patties?
They can be frozen after cooking and cooling. Place them in a freezer-safe container with parchment between layers. Reheat from thawed or frozen in an oven, skillet, or air fryer until hot and crisp.
