1-First Step: Get the pan and oven ready Preheat your oven to 350 degrees Fahrenheit. Grease an 8 x 8 baking dish so the egg bake releases easily after baking. This small step helps a lot later when it is time to cut clean squares. Before you mix anything, rinse and drain the quinoa. Even though it does not get cooked first, rinsing helps remove any bitter taste from the outside of the grain. That little bit of prep gives the quinoa spinach egg bake a cleaner flavor.

2-Second Step: Mix the egg base Grab a large bowl and whisk together the 8 eggs, 1 1/4 cups milk, 1 tablespoon chopped garlic, 1 teaspoon chopped thyme, 1/2 teaspoon salt, 1/2 teaspoon pepper, and 1/2 cup uncooked quinoa. Whisk until the mixture looks well blended and the eggs are fully broken up. This is where the dish starts to come together. The eggs and milk give you a soft, custardy base, while the quinoa will absorb liquid as it bakes.

3-Third Step: Add the spinach Stir in the 2 cups packed baby spinach, roughly chopped. The spinach may look like a lot at first, but it wilts down nicely in the oven. Make sure it is spread through the mixture so every slice has some green in it. If you want to switch things up, this is also the point where you can add chopped onion, diced peppers, mushrooms, or even small bits of ham. That makes the quinoa spinach egg bake a handy clean-out-the-fridge recipe.

4-Fourth Step: Pour and settle the mixture Pour the mixture into the greased baking dish. Cover it with foil, then shake the dish gently to settle the quinoa. This helps the grain spread evenly instead of sinking into one spot. The foil keeps moisture in during the first part of baking, which helps the eggs set without drying out. This is one of the reasons the texture stays soft in the center while still baking through properly.

5-Fifth Step: Bake until just set Bake for 45 minutes, or until the center is just set. The middle should no longer look wet, but it does not need to be browned yet. Watch the bake near the end so it does not overcook. Since oven times can vary, start checking a few minutes early if your oven runs hot. A gentle bake gives the best texture, especially in a dish with eggs and quinoa.

6-Final Step: Add cheese, finish baking, and serve Remove the foil, sprinkle the top with 1 cup finely shredded cheddar or swiss cheese, and bake uncovered for 10 to 15 minutes more. The cheese should melt into a golden, lightly crisp top. Let it cool briefly before slicing. This helps the pieces hold together better, especially if you plan to pack them for meal prep. Serve warm and enjoy the savory, cozy flavor of your quinoa spinach egg bake.
