How to Make Onion Kugel
-
Preheat your oven to 350°F (175°C). This ensures that the kugel cooks evenly and achieves that wonderful golden-brown top.
-
Beat the egg yolks in a large bowl on high speed until they become thick and lemon-colored, about 2 minutes. This step is crucial for creating a light and airy texture in your kugel.
-
Mix in the finely chopped onions, matzo meal, canola oil, salt, and pepper into the beaten egg yolks. Stir well until everything is fully combined, creating a flavorful batter.
-
Whip the egg whites in a separate bowl on high speed until stiff peaks form. This aeration is key to achieving that fluffy, soufflé-like consistency in your finished kugel.
-
Fold the whipped egg whites gently into the onion mixture using a spatula. Be careful not to deflate the whites as you combine them; this step ensures the kugel rises beautifully while baking.
-
Pour the combined mixture into an ungreased 2-quart round baking dish, spreading it evenly to ensure uniform baking.
-
Bake uncovered for 35-40 minutes, or until a knife inserted in the center comes out clean. The top should be a lovely golden brown and slightly crispy.
-
Serve immediately while hot, optionally garnishing with minced fresh parsley for a pop of color and flavor.
Optional: Add a sprinkle of extra herbs over the top for a burst of freshness.

Simply prepare the batter and refrigerate it in an airtight container. When you’re ready to serve, pour the mixture into your baking dish and bake as directed.

Onion Kugel Variations
Feel free to get creative and customize your onion kugel to suit your tastes and dietary needs!
-
Vegetable Blend: Replace onions with sautéed zucchini or chopped spinach for a refreshing twist. The added veggies bring a vibrant color and new flavor profile.
-
Gluten-Free: Swap matzo meal for gluten-free breadcrumbs or crushed gluten-free crackers. This option keeps the kugel deliciously fluffy for those with gluten sensitivities.
-
Cheesy: Incorporate 1 cup of grated cheese, like cheddar or mozzarella, for a rich, indulgent version. The melty goodness enhances the flavor and makes it even more comforting.

Smoky Flavor: Use smoked paprika instead of regular paprika to introduce a subtle smokiness. It pairs beautifully with the savory onions, creating an irresistible flavor combination.

Egg-Free: For a vegan version, use flax eggs (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water per egg) to replace the eggs. The idea is to maintain texture while catering to plant-based diets.
-
Nutty Crunch: Sprinkle 1/4 cup of toasted pine nuts or slivered almonds on top just before baking. This gives a delightful crunch and nutty flavor that complements the softness of the kugel beautifully.
Expert Tips for Onion Kugel
-
Perfect Egg Whites: Ensure your egg whites are beaten to stiff peaks. This step is vital for a light and airy onion kugel texture.
-
Gentle Folding: When combining the egg whites with the onion mixture, fold gently. This preserves the airiness from the whipped egg whites, ensuring a fluffy final product.

Sauté Onions: For an extra layer of flavor, sauté the onions in a small amount of oil before adding them to the batter. This enhances sweetness and depth.

Onion Kugel Recipe FAQs
How do I select the best onions for my kugel?
Absolutely! When picking onions for your onion kugel, look for firm bulbs with smooth, shiny skins. Avoid any that have dark spots or are sprouting. Yellow onions are commonly used due to their balance of sweetness and tang, but you can also use sweet onions for a milder flavor.
How can I store leftover onion kugel?
To keep your onion kugel fresh, store it in an airtight container in the refrigerator for up to 3 days. This method helps retain its delightful texture and flavor. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) until warmed through, about 15-20 minutes.
Can I freeze onion kugel, and if so, how?
Very! Freezing onion kugel is simple. Wrap the cooked kugel tightly in plastic wrap followed by aluminum foil to prevent freezer burn and label it with the date. It can be frozen for up to 3 months. When you’re ready to eat it, just thaw it in the fridge overnight before reheating in the oven at 350°F (175°C) for about 20-25 minutes.
What should I do if my kugel turns out dense instead of fluffy?
That can happen, but don’t fret! This usually occurs if the egg whites weren’t beaten to stiff peaks or were overmixed when folding them into the batter. For the fluffiest kugel, ensure the egg whites are light and airy and fold gently to maintain their structure. If you follow these steps, you should have a perfectly fluffy onion kugel next time!
Is onion kugel safe for my pets or do any allergies apply?
Very good thought! Generally, onion kugel isn’t safe for pets, particularly dogs and cats, as onions can be toxic to them. If you’re cooking for someone with allergies, be aware that this dish contains eggs and can contain gluten (if using regular matzo meal). Always consult with your guests on dietary restrictions before serving!
