Slice 2 large onions thinly. Heat 2 tablespoons of olive oil in a skillet over medium heat. Add the sliced onions, stirring occasionally for about 15-20 minutes until they are soft and golden brown.

Cook techniques
Caramelizing Onions
Caramelizing onions is a slow cooking process that enhances their natural sweetness. Begin by slicing onions thinly and cooking them in a pan over medium-low heat with a bit of oil or butter. Stir occasionally to prevent sticking, and continue cooking for 20-30 minutes until they are golden brown and caramelized.
Baking a Casserole
To bake a casserole, preheat your oven to the desired temperature, usually around 350°F (175°C). Assemble all ingredients in a baking dish, ensuring even distribution. Cover with foil to prevent excessive browning and bake until heated through and the top is golden, removing the foil in the last few minutes for a crispy finish.
Blanching Potatoes
Blanching potatoes involves briefly boiling them in salted water, followed by an ice bath to stop the cooking process. Peel and cut the potatoes into cubes, boil for about 4-5 minutes, then quickly transfer them to ice water to maintain their texture and color.
Layering Ingredients
Layering ingredients in a casserole helps in creating balanced flavors and textures. Start with a layer of vegetables, followed by proteins, and then top with starches (like potatoes or bread). Repeat layers as necessary, finishing with a layer that will create a crust when baked.
Setting the Casserole
Letting a casserole set after baking is critical for better slicing and serving. Allow the dish to cool slightly for about 10-15 minutes before cutting to let it firm up, making it easier to dish out without falling apart.
