Step‑by‑Step Instructions for Savory Southern Vegetarian Casserole

Step 1: Prep Vegetables
Begin by washing and chopping all your vegetables into bite-sized pieces. This includes vibrant bell peppers, fresh zucchini, and nutrient-packed spinach. Aim for even sizes to ensure consistent cooking. Set your prepped veggies aside in a large mixing bowl as you gather the rest of your ingredients.

Step 2: Mix Ingredients
In that same bowl, combine your chopped vegetables with a can of diced tomatoes, dried oregano, garlic powder, onion powder, and half of the cheddar cheese. Stir gently but thoroughly, ensuring every piece of vegetable is well-coated with the flavorful seasonings. This mixture will create a savory base for your casserole.

Step 3: Assemble Casserole
Grease a slow cooker or a casserole dish with a little cooking spray. Transfer the vegetable mixture into the dish, spreading it out evenly. To top off your casserole, sprinkle the remaining cheddar cheese generously over the surface, ensuring a delightful cheesy crust once cooked.

Step 4: Cook
Cover your slow cooker or casserole dish with a lid or aluminum foil to seal in the flavors. Cook on low heat for 6 to 8 hours. You’ll know it’s ready when the vegetables are tender and the cheese is beautifully melted. This slow cook will allow all those comforting flavors to meld perfectly.

Step 5: Serve
Once done, let the casserole cool for about 5 minutes, allowing the flavors to settle. When serving, scoop out portions with a spatula, making sure to get a mix of vegetables and gooey cheese in each serving. Pair your casserole with crusty bread or a fresh salad to complete this comforting vegetarian meal.
