Ingredients
For the casserole
- 2 medium potatoes, peeled and thinly sliced (use a mandoline for speed)
- 8 large eggs
- ¼ cup canned coconut milk (well shaken)
- 1 teaspoon sea salt
- Black pepper, to taste
- 1 pound compliant chicken sausage, cooked and crumbled
- 1 cup sliced mushrooms
- 1 red bell pepper, thinly sliced
- 4 cups fresh spinach
Optional add‑ins: ½ small onion (thinly sliced), ½ teaspoon garlic powder, ½ teaspoon smoked paprika, chopped parsley for garnish.
How to make
Step 1: Prep the base
Use a mandoline or sharp knife to thinly slice the potatoes. Lightly grease the crockpot insert. Lay potatoes in an even layer on the bottom to form a base.
Step 2: Mix the eggs
In a large bowl, whisk eggs, coconut milk, salt, and pepper until well combined.
Step 3: Layer the ingredients
Add half of the sausage, mushrooms, peppers, and spinach over the potatoes. Pour in half of the egg mixture. Repeat with the remaining sausage, veggies, and eggs to make two layers. (Spinach will wilt down as it cooks.)
Step 4: Cook (low effort)
Cover and cook on High for 2 hours, or until the center is set and edges pull slightly from the sides. (Slow cooker models vary; check starting at 1 hour 45 minutes.)
Step 5: Rest and portion
Let the casserole rest 10-15 minutes, then slice into 6 portions. Garnish if you like and pack into meal prep containers.

How to store
Freezer: Wrap portions tightly or store in freezer‑safe containers for 2-3 months. For best texture, freeze without leafy garnishes.
Fridge: Cool completely, then store portions in airtight containers for up to 4 days.
How to reheat
- Microwave: 60-90 seconds per slice from the fridge; 3-4 minutes from frozen (reheat at 50% power, then finish at full power). Rest 1 minute.
- Oven/toaster oven: 325°F for 10-15 minutes (fridge) or 25-30 minutes (frozen), covered with foil to keep moisture in. Uncover for the last 2-3 minutes if you like lightly crisp edges.
Tip: If reheating from frozen, thaw overnight in the fridge for the most even texture.

Helpful tips and ingredient swaps
- Slow cooker size: A 5-6 quart crockpot works best. In a larger cooker, check for doneness a bit earlier.
- Whole30 and dairy‑free: The base recipe is dairy‑free. Use a compliant chicken sausage and coconut milk.
- Swap the protein: Turkey sausage, crumbled bacon, or plant‑based sausage all work.
- Change the veg: Try zucchini, kale, or onions; keep total veg volume similar so the casserole sets.
- Make‑ahead shortcut: Cook sausage the day before; slice potatoes and store in cold water in the fridge (drain and pat dry before layering).

FAQs
Yes. Use 3-4 cups thawed, well‑drained hash browns. Pat dry before layering to avoid excess moisture.
Slice potatoes thinly, don't overpack with veggies, and let the casserole rest before slicing. If your slow cooker runs hot, check early to avoid overcooking.
Absolutely-about 1 to 1 ½ cups shredded cheese (cheddar, pepper jack, or dairy‑free shreds) sprinkled between layers. Skip for Whole30.
Yes. Thinly slice or use diced sweet potato; the cook time is the same. Flavor is slightly sweeter and pairs well with turkey sausage.
Up to 4 days in the fridge when stored properly. Reheat until steaming hot throughout before serving.

Final thoughts
Set it and forget it breakfasts are the secret to calmer mornings. With a single crockpot session, you'll stack six hearty portions that keep you fueled and focused all week long.

This sounds amazing, and I am so ready to try! Is there a reason why you opted for frozen spinach and not fresh?
It was delicious and will definitely make this again. We are going to try your Italian Chicken crockpot meal next!
Sarah Kesseli says
You can use either! It was what we had on hand at the time.
Megan Dorriety says
Can you use another type of milk for this?
Sarah Kesseli says
Hi Megan, You can, but it needs to be a full fat milk option to ensure that it doesn't get too dry. I hope that helps!

You list the ingredients but not how it's made. How long do I cook it?
