“Makes my whole week easier — creamy, flavorful, and reheats perfectly. A go-to for busy mornings.” — A reader review
The cooking process explained
Quick overview so you know what to expect before you start:
- Brown and crumble the turkey sausage; drain any excess fat.
- Whisk eggs, cottage cheese, garlic powder, salt and pepper until smooth.
- Stir in chopped spinach and shredded mozzarella.
- Combine cooked sausage with the egg mixture and pour into a greased baking dish.
- Bake at 350°F (175°C) until the center is set, about 30–40 minutes.
- Let rest 5–10 minutes, then slice and serve.
This keeps the assembly straightforward and helps you plan timing for sides or coffee while it bakes.
Key Ingredients
- 8 large eggs — the main structure. Use room temperature eggs if you have time for a fluffier texture.
- 1 cup cottage cheese — acts as a creamy binder; you can substitute ricotta for a milder, slightly sweeter result.
- 1 pound turkey sausage, crumbled — cook and drain before adding. Chicken sausage or a plant-based sausage work well as swaps.
- 1 cup shredded mozzarella cheese — melts nicely; try cheddar, pepper jack, or Gruyère for different flavor profiles.
- 1 cup chopped spinach — optional, wilts into the custard. Bell pepper, mushrooms, or diced tomatoes are tasty alternatives.
- 1 teaspoon garlic powder — a mild boost of savory flavor; adjust to taste.
- Salt and pepper to taste — fresh herbs (chives, parsley, or basil) are a great finish.
Notes: If you want lower sodium, choose low-sodium cottage cheese or reduce added salt. For creamier binding, briefly blend cottage cheese to smoothness.
Directions to follow
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish or similar-size casserole pan.
- Heat a skillet over medium heat. Add the turkey sausage and cook, breaking it into small pieces, until browned and cooked through (about 6–8 minutes). Drain excess grease and set aside.
- In a large bowl, whisk the eggs, cottage cheese, garlic powder, salt, and pepper until mostly smooth and uniform.
- Stir the shredded mozzarella and chopped spinach into the egg mixture. Fold in the cooked sausage until evenly distributed.
- Pour the mixture into the prepared baking dish, spreading it evenly.
- Bake in the preheated oven for 30–40 minutes, or until the center is set and the top is lightly golden. A knife inserted in the center should come out mostly clean; the internal temperature should reach 160°F (71°C) for safety.
- Remove from oven and let rest for 5–10 minutes before cutting into squares. Resting helps slices hold together.
If you like a browned top, broil 1–2 minutes at the end while watching closely.
Best ways to enjoy it
Serve slices warm or at room temperature. Pairing ideas:
- A simple mixed-greens salad or arugula with lemon vinaigrette for brightness.
- Toast, whole-grain English muffins, or a side of roasted potatoes for a heartier plate.
- Salsa, hot sauce, or avocado slices on top for extra flavor and texture.
If you’re curating a brunch spread, pair it with fruit salad and coffee, or consult this list of easy breakfast recipes for complementary dishes.
Storage and reheating tips
- Refrigerate: Cool the casserole to room temperature, cover tightly, and store in the fridge for up to 3–4 days.
- Freeze: Cut into portions, wrap well in plastic wrap and foil, or use airtight containers. Freeze up to 2–3 months. Thaw overnight in the fridge before reheating.
- Reheat: Oven — 325°F (160°C) until warmed through (about 15–20 minutes for a slice). Microwave — 1–2 minutes, depending on portion size; cover to retain moisture.
- Food safety: Refrigerate leftovers within 2 hours of baking. Reheat to 165°F (74°C) when serving.
Helpful cooking tips
- For a silkier base, briefly blend the cottage cheese with the eggs in a blender before mixing in sausage and spinach.
- Avoid sogginess: squeeze or sauté watery vegetables (like mushrooms or tomatoes) first to remove excess liquid.
- Don’t overbake: the casserole will firm up as it rests. Slight jiggle in the center is okay.
- Use a toothpick or thermometer to check doneness—better than relying on color alone.
- Make it in advance: assemble the night before, cover, and bake the next morning (add a few extra minutes if starting cold from the fridge).
Creative twists
- Vegetarian: Replace turkey sausage with crumbled tempeh or diced and seasoned tofu, or use a plant-based sausage.
- Southwestern: Add diced green chiles, pepper jack cheese, and cumin; top with salsa and cilantro.
- Mediterranean: Swap mozzarella for feta, add sun-dried tomatoes, spinach, and oregano.
- Potato base: Place a layer of shredded hash browns in the bottom of the pan for a heartier casserole.
- Low-carb: Keep the spinach but skip starchy add-ins; serve with a side salad.
FAQ – Your questions answered
Q: Can I use ricotta instead of cottage cheese?
A: Yes. Ricotta gives a slightly creamier, less tangy result. Texture will be similar—use 1 cup as a 1:1 substitute.
Q: How long does the casserole take from start to table?
A: Plan on about 10–15 minutes prep time and 30–40 minutes baking. Total ~45–60 minutes depending on your oven and whether you precook vegetables.
Q: Can I prepare this the night before?
A: Absolutely. Assemble the casserole, cover tightly, and refrigerate overnight. Bake the next morning; you may need to add 5–8 minutes to the bake time.
Q: Is it safe to reheat and eat leftovers multiple times?
A: Reheat only once. Store leftovers in the fridge for up to 3–4 days and heat to 165°F (74°C) before eating. Avoid reheating the same portion repeatedly.
Q: How many servings does this make?
A: A 9×13-inch casserole with these quantities typically yields 8 generous servings (about one egg per serving) — adjust portion size to suit your needs.
Q: Can I reduce the sodium?
A: Yes — choose low-sodium cottage cheese and turkey sausage, and omit added salt or use sparingly. Fresh herbs add flavor without extra salt.
