Instructions for Making White Bean & Veg Casserole

Let’s dive into the simple steps that make this casserole so comforting and flavorful.

1. Preheat Your Equipment:
Set your oven to 375°F (190°C) so it’s ready when you are.

3. Prepare Your Cooking Vessel:
Lightly grease a 9×13 inch casserole dish with olive oil or cooking spray.

4. Assemble the Dish:
Add the white beans and crushed tomatoes to the skillet. Sprinkle in Italian seasoning, salt, and pepper. Mix everything well, then pour into the casserole dish. Spread evenly and top with mozzarella cheese.

5. Cook to Perfection:
Bake uncovered for 25 to 30 minutes, or until the cheese is golden and bubbling.

6. Finishing Touches:
Let it rest for 10 minutes before serving. Sprinkle fresh herbs if you like.

Cooking Tips & Tricks

Here are some little details that make a big difference:

Use freshly grated cheese for better melt and stretch.
Add a splash of balsamic vinegar to the tomato base for depth.
Don’t skip the resting time after baking to let it firm up slightly.

What to Avoid

Overcrowding the dish: Spread ingredients evenly to avoid sogginess.
Skipping the seasoning: Beans need salt to shine.
