- Onion – Enhances the dish’s overall flavor; yellow or sweet onions are ideal for a richer taste.
- Garlic – Brings aromatic depth; fresh garlic is preferred for its vibrant flavor.

Step‑by‑Step Instructions for Amish Sweet Gold
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your casserole cooks evenly from the start, resulting in perfectly melted cheese on top. While the oven heats up, gather your ingredients and prepare your casserole dish by greasing it lightly with olive oil for easy serving later.
Step 2: Sauté the Aromatics
In a large skillet, heat a tablespoon of olive oil over medium heat. Once hot, add finely chopped garlic and diced onion, sautéing for about 3–5 minutes until the onions are translucent and fragrant. This step is crucial as it forms the flavorful base for your Amish Sweet Gold casserole.
Step 3: Cook the Vegetables
Next, toss in the diced bell peppers and continue to cook for another 5 minutes until they are tender. Then, gently stir in the fresh spinach, cooking until it wilts, which should take around 2 minutes. The vibrant colors and enticing aromas will start to fill your kitchen, signaling that you’re on the right track.
Step 4: Combine the Filling
In a large mixing bowl, combine the sautéed vegetable mixture with riced cauliflower and tomato sauce. Season the mixture with salt and pepper to taste. Stir thoroughly until all ingredients are well incorporated, creating a hearty filling for your low-carb Amish Sweet Gold casserole.
Step 5: Assemble the Casserole
Transfer the vegetable mixture into your greased casserole dish, spreading it evenly. Top off the mixture generously with mozzarella cheese, allowing it to form a beautiful, golden crust as it bakes. Make sure to cover the entire surface for maximum cheesy goodness.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 25–30 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and turns a lovely golden brown. The delightful scent wafting from the oven will be irresistible, making it hard to wait!
Step 7: Cool and Serve
After baking, carefully remove the casserole from the oven and let it sit for about 5 minutes. This resting time allows the layers to settle, making it easier to serve. Now, grab a spatula and dish up your scrumptious Amish Sweet Gold casserole to share with family and friends!

Expert Tips for Low-Carb Vegetarian Casserole
-
Roast for Flavor: Consider roasting the cauliflower beforehand to amplify its nutty notes. This simple step elevates the overall taste and aroma of your casserole.
-
Don’t Overcook Spinach: Keep the spinach vibrant and fresh by adding it towards the end of cooking. Overcooking results in a dull color and loss of nutrients.
-
Layer Wisely: For a beautifully browned crust, evenly layer the cheese on top. This ensures every bite is gooey, cheesy perfection while avoiding burnt edges.
-
Fresh Ingredients Are Key: Using fresh vegetables rather than frozen can enhance the dish’s flavor and texture. It also adds an element of festivity to your Amish Sweet Gold casserole!
-
Season Well: Don’t shy away from adjusting salt and pepper to taste. Let each ingredient shine through with the right seasoning, ensuring a delicious experience for everyone at the table.
Make Ahead Options
These Low-Carb Vegetarian Casseroles are a busy cook’s dream, perfect for meal prep! You can prepare the casserole filling (vegetables combined with cauliflower and tomato sauce) up to 24 hours in advance. Simply store the mixture in an airtight container in the refrigerator until you’re ready to bake. To maintain quality, keep the cheese separate until just before baking, as this prevents it from becoming soggy. When it’s time to serve, preheat your oven, layer the cheese on top, and bake for 25-30 minutes until bubbly and golden. This way, you can enjoy a homemade, comforting meal without the last-minute rush!

Amish Sweet Gold Recipe FAQs
What type of cauliflower should I use for the casserole?
Absolutely! You can use either fresh or frozen cauliflower; however, fresh cauliflower yields a better texture and flavor. Look for firm heads without dark spots. If using frozen, thaw it before ricing to avoid excess moisture in your casserole.
How should I store leftovers of the Amish Sweet Gold casserole?
For sure! Store your leftover casserole in an airtight container in the fridge for up to 3 days. Just reheat it in the oven at 350°F (175°C) for about 15-20 minutes until warmed through for the best results.
Can I freeze the Amish Sweet Gold casserole?
Yes, indeed! This casserole freezes wonderfully. Wrap it tightly in plastic wrap and then aluminum foil, or use a freezer-safe container. It will last for up to 2 months. Just thaw it overnight in the fridge before reheating for the best taste and texture.
What if my casserole comes out watery?
No worries! If your casserole is watery, it might be due to excess moisture from veggies, especially if using frozen spinach. To avoid this, make sure to sauté your vegetables properly and consider adding a little more cheese or riced cauliflower to help absorb some of that moisture.
Can I make this casserole dairy-free?
Very much so! You can easily keep the Amish Sweet Gold casserole dairy-free by using a dairy-free cheese alternative. I often recommend brands that melt well, like vegan mozzarella, to ensure that you still get that lovely creamy texture on top.
How do I keep the spinach fresh and vibrant?
Great question! To keep the spinach looking bright, add it to the skillet towards the end of the cooking process, just until it wilts. This prevents overcooking, which can lead to a dull color and loss of nutrients. Enjoy the flavorful and nutritious texture it brings!
