Step‑by‑Step Instructions for Southern Vegetarian Casserole
Step 1: Preheat and Prepare Vegetables
Begin by preheating your oven to 350°F (175°C). While it warms up, steam the cauliflower until it’s tender and easy to pierce with a fork, about 8–10 minutes. Once steamed, pulse the cauliflower in a food processor until it resembles rice. If using fresh spinach, sauté it in a skillet over medium heat for roughly 2–3 minutes until wilted.
Step 2: Combine the Ingredients
In a large mixing bowl, combine the riced cauliflower, sautéed spinach, softened cream cheese, shredded cheddar cheese, and the eggs. Stir everything together until well mixed and creamy, ensuring no lumps remain. Add garlic powder, onion powder, and paprika, adjusting the spice levels to your taste. This mixture should reflect the heartiness of a Southern vegetarian casserole.
Step 3: Transfer to Baking Dish
Grease a 9×13 inch baking dish with a little olive oil to prevent sticking. Pour the combined mixture into the dish, spreading it evenly with a spatula. Make sure the top is smooth, which will help it cook evenly throughout. You can add a sprinkle of additional cheddar cheese on top for an extra cheesy crust.
Step 4: Bake the Casserole
Place the baking dish in the preheated oven and bake for 30–35 minutes. You’ll know it’s done when the top is golden brown and the edges are slightly crisp. The center should be set, and a gentle jiggle should show a firm and cohesive texture, indicative of a perfectly baked Southern vegetarian casserole.
Step 5: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool on a wire rack for about 5–10 minutes. This cooling period helps firm up the casserole for easier slicing. Serve warm, garnished with fresh herbs like parsley or chives, if desired, to elevate the flavors of your comforting Southern-inspired dish.

Storage Tips for Southern Vegetarian Casserole
Fridge: Store leftovers in an airtight container for up to 3 days, keeping the casserole fresh and ready for a quick meal.
Freezer: You can freeze the casserole before baking, wrapped tightly in plastic wrap and foil, for up to 3 months. Thaw in the fridge overnight before baking.
Reheating: To reheat, bake from thawed at 350°F (175°C) for 20–25 minutes or until heated through, ensuring it remains moist and flavorful.
Serving: Garnish with fresh herbs before serving for a pop of color and added flavor that will enhance your comfort food experience.
Make Ahead Options
The Southern Vegetarian Casserole is a fantastic candidate for meal prep, making your busy weeknights a breeze! You can prep the entire casserole up to 24 hours in advance. Simply follow the steps to combine the riced cauliflower, sautéed spinach, cream cheese, cheddar, and eggs, then transfer it to your greased baking dish. Cover it tightly with plastic wrap and refrigerate until you’re ready to bake. This way, the flavors meld beautifully, and you’ll save precious time when it’s time to serve. When you’re ready to eat, just pop it in the oven and bake as directed—your casserole will emerge just as delicious and comforting as if made fresh!
Expert Tips for Southern Vegetarian Casserole
- Riced Cauliflower Care: Ensure cauliflower is thoroughly riced for an even texture. Avoid over-processing as it can become mushy, ruining the casserole’s structure.
- Gentle Mixing: When combining ingredients, mix gently to avoid a tough texture. You want a creamy consistency, not a dense one.
- Cooling Time: Allow the casserole to sit for a few minutes after baking. This helps it firm up, making it easier to slice beautifully and serve.
- Cheese Choices: Feel free to experiment with different cheeses for added flavor. Using a blend can bring delightful complexity to your Southern vegetarian casserole.
- Fresh Spinach Tip: If using fresh spinach, ensure to wilt and drain it well. This prevents excess moisture that can make your casserole soggy.

What should I do if my casserole turned out too watery?
If you find your casserole is too watery, there are a couple of tricks you can employ. Firstly, make sure to thoroughly drain any thawed frozen vegetables, especially spinach, to prevent excess moisture. If it’s too late, consider baking the casserole an additional 5-10 minutes to help evaporate some of that liquid.

While this dish is vegetarian, it contains dairy (cream cheese and cheddar), which can be a concern for those who are lactose intolerant. You can use vegan cheese alternatives or omit the cheese entirely for a dairy-free option. Additionally, if you want to make it gluten-free, just ensure that the spices you use don’t contain any hidden gluten.
Can I use a different type of cheese in the casserole?
