Step‑by‑Step Instructions for Cottage Cheese and Onion Bake
Step 1: Caramelize Onions
Melt 2 tablespoons of butter in a large skillet over medium-low heat. Add thinly sliced yellow onions and cook for 30-40 minutes, stirring frequently until they become deeply golden and jammy in texture. This slow cooking process will enhance their natural sweetness, creating that delightful caramelized flavor essential for your Cottage Cheese and Onion Bake.
Step 2: Drain Cottage Cheese
While the onions are caramelizing, set a fine-mesh strainer over a bowl and add the cottage cheese. Allow it to drain for at least 20 minutes, pressing gently with a spoon occasionally to remove excess liquid. This step is crucial to achieving a firmer texture in your bake, preventing it from becoming watery.
Step 3: Preheat Oven
Preheat your oven to 375°F (190°C). While the oven heats up, take a 9-inch pie dish and generously grease it with butter or cooking spray. This will ensure that your Cottage Cheese and Onion Bake releases easily after baking, allowing for neat, clean slices.
Step 4: Blend Custard Base
In a blender, combine the drained cottage cheese, 3 eggs, and 2 tablespoons of cornstarch. Blend until the mixture is smooth and frothy, which typically takes about 1-2 minutes. A well-blended custard base will create that rich creaminess in your bake, contributing to an enjoyable texture.
Step 5: Combine Ingredients
Transfer the blended mixture to a large mixing bowl, and stir in the caramelized onions, a handful of fresh thyme, salt, and pepper to taste. Finally, fold in ¾ cup of grated Gruyère cheese for a nutty richness. Ensure everything is evenly mixed to distribute the flavors throughout the Cottage Cheese and Onion Bake.
Step 6: Bake
Pour the mixture into the prepared dish and spread it evenly. Top with the remaining ¼ cup of Gruyère cheese for a lovely, cheesy crust. Bake in the preheated oven for 35-40 minutes, or until the edges are golden and the center slightly wobbles when shaken. This visual cue indicates that the bake is perfectly set.
Step 7: Cool
Once baked, remove the dish from the oven and let it rest on a wire rack for 10-15 minutes. This cooling period will help the flavors meld and make slicing much easier. After the wait, cut into wedges for serving, showcasing the creamy interior of your Cottage Cheese and Onion Bake.

Make Ahead Options
These Cottage Cheese and Onion Bakes are perfect for busy meal prep, allowing you to enjoy homemade comfort with less last-minute effort! You can caramelize the onions and drain the cottage cheese up to 24 hours in advance, storing them separately in airtight containers in the refrigerator to maintain their quality (this prevents the onions from becoming mushy and the cottage cheese from splattering). When you’re ready to prepare the bake, simply blend your custard base and combine all the ingredients. Then pour the mixture into your dish and bake; it will be just as delicious as if made fresh! This strategy not only saves you time but also ensures you can indulge in this protein-packed delight on a busy weeknight.
