Deviled Eggs With Caramelized Onions: A Chef’s Special

The first time I tasted a truly exceptional deviled egg was at a summer picnic, years ago. A dear family friend, known for her unassuming culinary brilliance, presented a platter of these seemingly simple appetizers. But one bite revealed a world of flavor – the creamy yolk filling, balanced by a sweet, savory depth that I couldn’t quite place. It turned out her secret was caramelized onions, adding a layer of complexity that transformed a classic into something truly unforgettable. These Caramelized Onion Deviled Eggs bring me right back to that summer day, and I’m excited to share this recipe with you.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 30 minutes
• Total Time: 1 hour
• Servings: 24 appetizers
• Yield: 24 deviled eggs
• Dietary Type: Gluten-Free

Ingredients

• 2 tablespoons butter
• 2 tablespoons olive oil
• 1 large Spanish onion, diced small
• 1 teaspoon sugar
• 12 eggs
• 1 cup nonfat yogurt, plain, Greek style, drained (see notes below)
• 1 pinch salt
• 1 pinch pepper
• 2 tablespoons chives, chopped

Ingredient Notes:

• For the yogurt, using Greek-style gives a thicker and richer texture than regular yogurt. If you’re using regular yogurt, make sure to drain it in cheesecloth or a fine-mesh sieve for about 30 minutes to remove excess liquid. This will ensure your filling isn’t too runny.
• If you’re not a fan of yogurt, you can substitute with mayonnaise, sour cream, or a combination of both.

Equipment Needed

• Medium skillet
• Mixing bowl
• Serving platter
• Ziptop bag (optional, for filling eggs)
• Paper towels

Instructions

1. Caramelize the Onions: Heat a medium skillet over low heat. Add the butter and olive oil. Once the butter has melted, add the diced Spanish onion. Sprinkle with the sugar.
2. Cook the Onions: Cook over low heat for 30 minutes or more, stirring occasionally, until the onions are dark and caramelized. It’s crucial to maintain a low heat to prevent burning. Don’t stir too much, as this will inhibit browning, but keep a close eye on them to prevent sticking. You’re aiming for a deep golden-brown color and a sweet, concentrated flavor.
3. Drain the Onions: Once the onions are caramelized, remove from heat and drain on paper towels to remove excess oil.
4. Hard-Cook the Eggs: Place the eggs in a saucepan and cover with cold water. Bring the water to a rolling boil, then immediately remove from heat, cover, and let stand for 12 minutes. This method helps prevent the yolks from turning green and makes the eggs easier to peel.
5. Cool and Peel the Eggs: After 12 minutes, drain the hot water and immediately rinse the eggs under cold running water until they are cool enough to handle. Peel the eggs.
6. Prepare the Eggs: Cut each egg in half. Place the yolks in a mixing bowl, and arrange the whites on a serving platter.
7. Make the Filling: With a fork, mash the yolks in the mixing bowl until they are smooth. Add the caramelized onions and about 1/2 cup of the yogurt. Stir to combine.
8. Adjust the Consistency: Stir in more yogurt (up to 1 cup total) until the mixture reaches a creamy consistency. Taste and season lightly with salt and pepper. Remember that the caramelized onions already contribute a significant amount of flavor, so don’t over-season.
9. Fill the Eggs: The easiest way to fill the eggs neatly is with a ziptop bag. Open the bag and fold the top over the outside. Scrape the filling into the bag, pushing it well into a bottom corner. Close the bag, making sure to squeeze out as much air as possible. Cut a small hole in the bottom corner and gently squeeze the filling into each egg white.
10. Garnish: Top each deviled egg with a sprinkle of chopped chives.
11. Chill and Serve: Refrigerate the deviled eggs until ready to serve. Chilling allows the flavors to meld together and makes them even more delicious.

Expert Tips & Tricks

• Egg Peeling Perfection: For easy-to-peel eggs, try adding a teaspoon of baking soda to the water while boiling. The baking soda helps to loosen the membrane between the egg and the shell.
• Even Caramelization: The key to perfect caramelized onions is patience. Don’t rush the process by turning up the heat. Low and slow is the way to go, allowing the onions to develop their natural sweetness and rich, brown color.
• Filling Consistency: If your filling is too thick, add a little more yogurt or even a tiny splash of milk until you achieve the desired consistency. If it’s too thin, try adding a bit of mashed hard-boiled yolk.
• Make Ahead Tip: To save time, you can hard-cook the eggs and caramelize the onions a day or two in advance. Store them separately in the refrigerator until you’re ready to assemble the deviled eggs.
• Presentation Matters: Use a piping bag with a decorative tip to fill the egg whites for a more elegant presentation.

Serving & Storage Suggestions

Serve these deviled eggs chilled. They make a wonderful appetizer for parties, potlucks, or holiday gatherings.

• Room Temperature: Deviled eggs should not be left at room temperature for more than two hours, as they can become a breeding ground for bacteria.
• Refrigerator: Store leftover deviled eggs in an airtight container in the refrigerator for up to 2-3 days.
• Freezer: Freezing is not recommended as it changes the texture of the egg whites and filling.

FAQs (Frequently Asked Questions)

Q: Can I make these deviled eggs ahead of time?

A: Yes, you can hard-cook the eggs and caramelize the onions a day or two in advance. Store them separately in the refrigerator until you’re ready to assemble the deviled eggs. However, it’s best to fill the eggs just before serving to prevent the whites from becoming watery.

Q: Why are my caramelized onions burning instead of caramelizing?

A: Burning usually indicates that the heat is too high. Make sure to cook the onions over low heat, stirring occasionally, to prevent them from sticking and burning.

Q: Can I use a different type of onion?

A: While Spanish onions are recommended for their sweetness, you can use other types of onions like yellow or Vidalia. Keep in mind that the flavor will be slightly different.

Q: My deviled egg filling is too runny. How can I fix it?

A: If your filling is too runny, try adding a bit of extra mashed hard-boiled yolk or a spoonful of plain cream cheese to thicken it up.

Q: How can I prevent the yolks from turning green around the edges?

A: Overcooking the eggs is the main cause of green yolks. Follow the recommended hard-cooking method and immediately cool the eggs in cold water to prevent overcooking.
