Step‑by‑Step Instructions for Dairy-Free Breakfast Casserole
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grab a 9×13 casserole dish and generously grease it with non-stick spray or a bit of butter to prevent sticking. This step is crucial for ensuring your Dairy-Free Breakfast Casserole comes out perfectly golden and easy to slice.
Step 2: Prepare the Hashbrowns
Evenly distribute the thawed hashbrowns across the bottom of the greased casserole pan, pressing them down lightly to create a solid base. Ensuring the hashbrowns are well-coordinated is essential for achieving that hearty texture throughout. You want them to be slightly crispy on the edges post-baking, ready to soak up the delicious flavors.
Step 3: Cook the Sausage
In a sauté pan over medium heat, warm your chosen sausage until fully cooked and browned, which should take about 5–7 minutes. Be sure to break the sausage into small pieces for better distribution in the casserole. Once cooked, remove the pan from heat and spread the sausage evenly over the prepared hashbrowns, followed by the diced onions and half of the dairy-free cheese for extra flavor.
Step 4: Mix the Egg and Milk
In a medium mixing bowl, whisk together the eggs, dairy-free milk, garlic powder, salt, and black pepper until well combined, about 1–2 minutes. This mixture will serve as the magically binding agent in your Dairy-Free Breakfast Casserole. Make sure all ingredients are thoroughly mixed for even seasoning and creamy goodness.
Step 5: Combine the Mixtures
Pour the egg mixture evenly over the hashbrown and sausage layers in the casserole dish, ensuring it seeps into all crevices. Top it off with the remaining dairy-free cheese to create a bubbly, cheesy top as it bakes. The combination of these elements is what makes this breakfast casserole a standout dish!
Step 6: Bake the Casserole
Carefully place your casserole in the preheated oven and bake for 45–55 minutes. You’ll know it’s ready when the center is fully set, and the top is beautifully golden brown. If you notice it browning too quickly, don’t hesitate to cover it loosely with foil to prevent burning while ensuring it cooks through.
Step 7: Cool & Serve
Once baking is complete, remove your Dairy-Free Breakfast Casserole from the oven and let it cool for 10–15 minutes before slicing. This resting time allows the flavors to meld and makes serving easier. Slice into squares, and prepare for smiles as you serve up this comforting brunch favorite!

Make Ahead Options
These Dairy-Free Breakfast Casserole preparations are perfect for busy mornings or brunch gatherings! You can assemble the casserole up to 24 hours in advance by following the complete recipe steps, then cover it tightly and refrigerate. For optimal quality, it’s best to bake it within this timeframe; this way, the flavors will meld beautifully without losing texture. When you’re ready to serve, simply preheat your oven to 350°F and bake for 45-55 minutes straight from the fridge, or add a few extra minutes if it’s cold. This make-ahead option will ensure you enjoy a warm and delicious breakfast with minimal effort, saving you time and letting you focus on spending time with loved ones!

Expert Tips for Dairy-Free Breakfast Casserole
• Customization Options: Feel free to experiment with different vegetables and proteins to suit your taste. Adding cooked spinach or bell peppers can enhance nutrition.
• Avoid Sogginess: Ensure you fully cook the sausage and allow the casserole to rest before slicing. This prevents a mushy texture and helps ingredients set.
• Storage Solutions: Leftovers can be stored in the fridge for up to 4 days or frozen for up to 1 month. Reheat from frozen by baking at 350°F for 20–30 minutes.
• Layering Techniques: Spread the hashbrowns evenly, and mix the egg mixture well for consistent flavor throughout the casserole. Proper layering makes a difference!
• Check Doneness: If in doubt, insert a knife into the center; it should come out clean when fully cooked. This ensures your Dairy-Free Breakfast Casserole is perfect every time.

Dairy-Free Breakfast Casserole Recipe FAQs
How do I select the best hashbrowns for my casserole?
Absolutely! When choosing hashbrowns, look for those that are evenly cut and have a golden appearance. Avoid any that have dark spots all over, as this can indicate freezer burn. I often recommend using thawed frozen hashbrowns for convenience, but if you’re feeling adventurous, fresh potatoes can be shredded as an alternative.
What is the best way to store leftovers?
To keep your Dairy-Free Breakfast Casserole fresh, store it in an airtight container in the fridge for up to 4 days. Be sure it has cooled completely before sealing to avoid condensation that makes it soggy. If you have a lot of leftovers, feel free to portion them out in single-serving containers for easy access!
Can I freeze my breakfast casserole?
Yes, the casserole can be frozen for up to 1 month! After baking, let it cool completely, then wrap it tightly with plastic wrap and aluminum foil to prevent freezer burn. When you’re ready to enjoy it, simply preheat the oven to 350°F and bake from frozen for about 20–30 minutes or until heated through.
What should I do if the casserole is too watery?
If your casserole turns out too watery, this could be due to the moisture content in the vegetables. To avoid this next time, make sure to sauté any vegetables you add so they release excess moisture beforehand. Additionally, letting the casserole rest after baking can help the ingredients set together beautifully.
Are there any allergy considerations with this recipe?
Very! This Dairy-Free Breakfast Casserole is already designed to be gluten-free and dairy-free. Always double-check your ingredient labels if you’re serving individuals with specific allergies, such as nut allergies (in the plant-based milk) or gluten sensitivity if using processed products.
How long does it take to reheat from frozen?
When reheating a frozen Dairy-Free Breakfast Casserole, preheat your oven to 350°F, then bake it for about 20–30 minutes or until it’s warmed through. For best results, bake it covered with foil to ensure even heating. Enjoy your delightful brunch creation!
