Ingredients You’ll Need
- 2 large eggs
- 2 tablespoons milk or unsweetened plant milk
- 3 tablespoons low-fat cottage cheese or plain Greek yogurt
- 1/3 cup cooked, diced turkey breast or cooked shredded chicken
- 1/4 cup shredded mild cheddar or mozzarella (optional)
- 1/3 cup baby spinach, roughly chopped
- 2 tablespoons finely chopped onion or shallot, softened
- 1 small cooked, peeled potato or 1/4 cup cooked sweet potato, diced (optional)
- 1 teaspoon olive oil or light butter for sautéing
- Salt and pepper to taste
- Fresh herbs (parsley or chives) or a pinch of dried thyme
You can serve this casserole with soft toast, warm oatmeal, or a spoonful of mashed potatoes if you like.
Step-by-Step Recipe
- Preheat oven to 350°F (175°C). Lightly grease a small ovenproof dish or two ramekins (about a 6-inch pan or two 8-oz ramekins).
- In a small skillet, warm the olive oil over medium-low heat. Add the onion and sauté until soft and translucent, about 3–4 minutes. Add spinach and cook 1 minute more until wilted. Remove from heat and let cool slightly.
- In a bowl, whisk the eggs, milk, and cottage cheese or yogurt until combined and a bit frothy. Stir in herbs, pepper, and just a pinch of salt or none if reducing sodium.
- Fold in the cooked turkey, sautéed vegetables, optional potato, and half the cheese.
- Pour the mixture into the prepared dish. Sprinkle the remaining cheese on top if using.
- If making ahead: cover tightly and refrigerate up to 24 hours. To freeze: assemble in a foil container, cover, and freeze up to 1 month.
- To bake: place dish in oven and bake 22–28 minutes, until set and lightly golden. For two small ramekins, check at 18–22 minutes. A knife inserted in the center should come out mostly clean.
- Let rest 3–5 minutes before serving to make it easier to cut and gentler to eat.
