Ingredients
  

  • 2 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter (or avocado oil for dairy-free)
  • 1 tablespoon olive oil (helps prevent burning)
  • 1/2 teaspoon salt, plus more to taste
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder (boosts onion flavor)
  • 1/4 teaspoon smoked paprika (optional, for depth)
  • 1 teaspoon Worcestershire sauce (or coconut aminos/tamari for gluten-free; check labels for carbs)
  • 1 teaspoon apple cider vinegar or lemon juice (brightens)
  • 8 ounces cream cheese, softened
  • 1 cup sour cream
  • 2 tablespoons mayonnaise (preferably avocado oil mayo)
  • Fresh chives or green onions, finely minced, for garnish
  • Optional: pinch of sweetener like allulose or erythritol if your onions aren’t sweet enough after caramelizing

Method
 

  1. Prepare the onions. Slice onions thinly and as evenly as possible. This helps them cook at the same rate and prevents burning.
  2. Start caramelizing. Heat butter and olive oil in a large skillet over medium heat. Add onions and 1/2 teaspoon salt. Cook, stirring every few minutes, until they soften and turn translucent, about 10 minutes.
  3. Go low and slow. Reduce heat to medium-low. Continue cooking 25–35 minutes, stirring occasionally. If the pan looks dry or onions start to scorch, add a tablespoon of water and stir. You’re aiming for deep golden-brown, jammy onions.
  4. Season the onions. Stir in black pepper, garlic powder, onion powder, and smoked paprika. Cook 1–2 minutes until fragrant.
  5. Deglaze and balance. Add Worcestershire (or tamari/coconut aminos) and apple cider vinegar. Scrape up browned bits. Taste and adjust salt. If needed, add a tiny pinch of keto-friendly sweetener to round out any bitterness.
  6. Cool the onions. Transfer onions to a plate and let them cool to at least room temperature. Warm onions will melt the dairy and loosen the dip too much.
  7. Make the creamy base. In a mixing bowl, beat softened cream cheese until smooth. Add sour cream and mayonnaise. Mix until completely creamy and lump-free.
  8. Combine. Fold in the cooled onions, reserving a spoonful for garnish if you like. Mix well so the flavor distributes evenly.
  9. Chill for best flavor. Cover and refrigerate at least 1 hour, ideally 4 hours or overnight. This resting time lets the onion flavor bloom.
  10. Finish and serve. Stir the dip, taste, and adjust salt, pepper, or acidity. Top with reserved onions and a sprinkle of fresh chives or green onions. Serve with cucumber slices, celery sticks, bell pepper strips, pork rinds, or keto seed crackers.
