Heat neutral oil in a large cast iron or stainless steel skillet over high heat.
Add the thinly sliced onions to the hot pan and season with a generous pinch of salt.
Sauté the onions, stirring occasionally, until they begin to soften and brown, and a fond (browned bits) forms on the bottom of the pan.
Push the onions to one side of the pan and add a splash of water to the empty side to deglaze. Scrape the fond from the bottom and stir it into the onions.
Repeat the process of allowing a fond to form and deglazing with water until the onions are deeply caramelized and dark brown.
Remove the caramelized onions from the skillet and place them in a bowl to cool down.
In a blender, combine the cottage cheese, Greek yogurt, mayonnaise, salt, black pepper, and optional cayenne pepper.
Blend on high speed until the mixture is completely smooth and creamy, with no lumps remaining.
Pour the blended base into a mixing bowl. Add the cooled caramelized onions.
Stir until the onions are evenly distributed throughout the dip. Taste and adjust seasoning with more salt if needed.
Transfer the dip to an airtight container and chill in the refrigerator for at least 3 hours to allow the flavors to meld.
Serve chilled with ridged potato chips or your favorite vegetables.

Use a food processor or blender to blend cottage cheese and Greek yogurt until completely smooth, 1–2 minutes.
Regular yogurt works but will make the dip thinner and less tangy. Drain it through cheesecloth first for better texture.
Serve chilled or at room temperature with ridged potato chips, crackers, or fresh vegetables for dipping.
