Ingredients Breakdown
Cream cheese: The base for a silky, rich texture, use full-fat for the best structure.
Caramelized onions: The flavor powerhouse. Slow-cooked until golden, sweet, and jammy.
Sharp cheddar cheese: Adds that familiar comfort and tang. Gruyère, Havarti, or Swiss are great alternatives.
Eggs: Bind the cheesecake and create a custardy interior.
Sour cream or heavy cream: Keeps the texture smooth and adds richness.
Butter: Helps caramelize the onions perfectly and adds depth to the crust (if using).
Crust (optional): A base made from crushed crackers, breadcrumbs, or puff pastry, adds structure and contrast.
Fresh thyme or chives: Optional herbs that elevate the flavor beautifully.
Salt & black pepper: Simple seasoning to balance the sweetness of the onions and richness of the cheese.
Step-by-Step Cooking Guide
- Caramelize the onions:
Slice 2–3 large yellow onions thinly. Melt butter in a skillet over medium-low heat. Add onions, a pinch of salt, and cook slowly for 25–30 minutes until deeply golden and jammy. Stir occasionally and deglaze with a splash of water or white wine if needed. - Prepare the crust (optional):
Mix 1 ½ cups crushed butter crackers or breadcrumbs with ¼ cup melted butter. Press into the bottom of a springform pan. Bake at 350°F (175°C) for 10 minutes to set. - Make the filling:
In a bowl, beat cream cheese until smooth. Add eggs one at a time, then mix in sour cream and shredded cheese. Stir in caramelized onions and season with salt, pepper, and thyme. - Bake the cheesecake:
Pour the mixture into the crust and smooth the top. Bake at 325°F (165°C) for 40–45 minutes, or until just set with a slight jiggle in the center. - Cool:
Let cool completely at room temperature, then refrigerate for at least 4 hours (or overnight) to firm up. - Serve:
Slice and serve at room temperature, topped with extra caramelized onions and fresh herbs if desired.
Tips, Variations & Add-Ons
- Use different cheeses: Gruyère, fontina, or smoked gouda give fun variations.
- Add crunch: Sprinkle crispy fried onions on top before serving.
- Go crustless: For a gluten-free version, skip the crust and bake directly in the pan.
- Add bacon or pancetta: For a smoky, salty depth.
- Make minis: Bake in muffin tins for bite-sized party versions.
- Herb it up: Mix in rosemary, thyme, or even green onions for extra flavor.
