Caramelized Onion Cheese Ball with Walnuts

Caramelized Onion Cheese Ball

Fresh onions cook down until deep golden and sweet, then cool before being folded into a cream cheese and sharp white cheddar base. Chilling turns the mixture into one large, spreadable cheese ball; a thick coating of chopped walnuts adds a crunchy exterior. Cook away the onions’ moisture and let them cool completely so the ball holds its shape.

Makes 12 appetizer servings. Allow about 20 minutes of active prep, 30–40 minutes to cook the onions, about 20 minutes to cool them, and at least 2 hours to chill the ball.

Ingredients for Caramelized Onion Cheese Ball

• 2 medium yellow onions, thinly sliced (about 300g)
• 1 tablespoon unsalted butter (15g)
• 2 packages full-fat cream cheese (8 ounces each), softened (450g total)
• 1 cup freshly grated sharp white cheddar (about 115g)
• 1 teaspoon Worcestershire sauce
• 1 teaspoon dried parsley
• 1/4 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon freshly ground black pepper
• 1 cup chopped walnuts (about 110g)

For serving: sturdy square crackers and a spreading knife.

How to Make Caramelized Onion Cheese Ball

1. Brown the onions: Melt the butter in a 10- to 12-inch skillet over medium-low heat. Add the onions and cook uncovered for about 30–40 minutes, stirring every few minutes and more often as they darken. Start checking for sticking after about 20 minutes. If browned bits threaten to scorch, add 1–2 tablespoons of water and scrape them up. Continue until the onions are soft, substantially reduced, deep golden brown, and free of pooled liquid.
2. Cool and chop: Spread the onions out and let them cool completely, about 20 minutes. Chop any long strands into small pieces so they distribute through the cheese.
3. Mix the cheese: Stir the softened cream cheese, cheddar, Worcestershire sauce, parsley, salt, and pepper until evenly combined. Fold in the cooled onions. Taste and add more salt if needed; the mixture should be thick enough to mound.
4. Shape and chill: Transfer the mixture to plastic wrap and gather it into one large, rounded ball. Wrap tightly and refrigerate for at least 2 hours, or until firm enough to unwrap without slumping. If it is still soft, keep it wrapped and chill it longer.
5. Coat and serve: Spread the walnuts on a shallow plate. Unwrap the ball and press the nuts over its entire surface, leaving little cheese exposed. Set it on a serving plate with square crackers and a spreading knife. Let it stand for 15–20 minutes before serving so the center is easier to spread.

How Brown Should the Onions Be?

Soft or translucent onions still hold too much moisture for this cheese ball. Cook them until they are deep golden, much smaller in volume, and no longer wet. A wide skillet helps moisture escape; a crowded pan may take longer. Let the onions cool until no warmth remains before adding them to the cheese, since warm or damp onions can loosen the mixture.

When to Add the Walnuts

If making the cheese ball ahead, refrigerate it wrapped and uncoated. Press on the walnuts shortly before serving to keep the coating distinct and chunky. For another walnut-coated option, see this blue cheese and walnut cheese ball.

Serving and Storage

Serve with sturdy square crackers and a spreading knife. The brief stand after refrigeration makes the cheese easier to spread without breaking the crackers.

Keep leftovers covered in the refrigerator and plan to use them within 3–4 days. For the best walnut texture, store any cheese ball made ahead without its coating and add the nuts near serving time. Do not reheat. Freezing is not recommended because the texture of this fresh-onion version after thawing is uncertain.
