Step-by-Step Instructions

This is one of those recipes where the process matters just as much as the ingredients.
Skip a step or rush through the whisking, and you'll end up with something flat and forgettable. But follow the rhythm here, and you'll pull out a casserole that's puffy, golden, and exactly what breakfast should feel like.
Beat the eggs until fluffy. Use a whisk or hand mixer and go longer than you think you need to. You want the eggs to lighten in color and increase in volume. This is what gives the casserole its signature airy texture.
10 Large Eggs
Stir in the melted butter. Make sure it's cooled down first; about 5 minutes. If it's too hot, it'll cook the eggs and you'll have scrambled lumps instead of a smooth base. Mix until it's fully incorporated and the eggs look glossy.
1/2 Cup Salted Butter
Add the flour, baking powder, salt, onion powder, and cottage cheese. Whisk everything together until the mixture is smooth and cohesive. The cottage cheese will break down a bit as you whisk, which is exactly what you want. No chunky curds floating around.
½ Cup All-Purpose Flour, 1 Teaspoon Baking Powder, 1/2 Teaspoon Salt, 1 Teaspoon Onion Powder, 2 Cups Cottage Cheese
Fold in the shredded cheddar. Use a spatula and be gentle here. You're not trying to whisk it in aggressively. Just fold until the cheese is evenly distributed throughout the batter. The mixture will be thick and a little lumpy from all that cheese, and that's perfect.
4 Cups Shredded Cheddar Cheese
Pour into a greased 9x13 pan or 12 greased muffin cups. If you're using a baking pan, make sure you grease it well. Butter or nonstick spray both work. If you're going the muffin route, fill each cup about three-quarters full so there's room for the puff.
Sprinkle fresh chives or green onion on top. This is optional, but it adds a nice visual contrast and a hint of sharpness that balances all the richness.
Fresh Chives
Bake at 350°F for 40 to 45 minutes. The casserole is done when the top and edges are deeply golden and the center is set. If you're using muffin tins, start checking around 25 to 30 minutes since they'll cook faster.
Let it rest for 5 minutes after pulling it from the oven. This gives the cheese a chance to firm up slightly so the casserole doesn't fall apart when you slice it. It also makes it easier to handle without burning your mouth.

How to Know It's Done

Forget the timer for a second and trust your eyes and your nose.

The top should be a deep golden yellow, almost bordering on amber at the edges. You're looking for color, not just paleness. That golden crust is where all the flavor lives. The sides should pull away from the pan just slightly, and if you gently shake the dish, the center should jiggle only a tiny bit, like set custard, not liquid batter.

If you want to be extra sure, insert a toothpick or knife into the center. It should come out clean or with just a few moist crumbs, no wet egg streaks. And the smell? You'll know. It'll smell buttery, cheesy, and almost toasty, like the edges are crisping up just right.

If you're baking in muffin tins, the tops will dome and turn golden brown. They should feel firm to the touch, not squishy. Let them cool in the pan for a few minutes before popping them out, or they might collapse from being handled too soon.

The worst thing you can do is pull it too early. Undercooked egg casserole is wet and dense. Fully cooked egg puff casserole is light, fluffy, and holds its shape when you slice it. Wait for that golden color and firm center, and you're golden.
