My vegetarian orzo casserole is a simple low-calorie meal that packs a punch. Flavored with paprika and oregano, you’ll be eating your daily recommended vegetables without realizing it. It will keep you warm in the winter and feeling fit and healthy in the summer. Make it part of your go-to recipes.


Prepared vegetables for the casserole
  • 2 minced garlic cloves
  • 2 cups of chopped onions
  • 3 large bell peppers
  • 14 celery sticks
  • 2 cups of shredded carrots
  • 1 cubed zucchini
  • 3 cups of sliced mushrooms
  • 4 oz of orzo
  • 3 tbsp of tomato puree
  • 28 oz of diced canned tomatoes
  • 4 cups of turkey bouillon
  • 4 tbsp of paprika
  • 3 tbsp of whole oregano


  1. Chop all the vegetables to the desired size
  2. Mix all the ingredients, except the orzo, and cook for 2 hours in the slow cooker
  3. Add in the orzo and cook for a further 30 minutes
  4. Serve

Serving Suggestions

Vegetarian Orzo casserole is a dish that can be the main component or be a side dish. The orzo component is minimal, so it can be served with another starch such as potatoes or rice (shown above). If you are looking for greater protein, this would be delightful with chicken, tofu, or a meatier fish.

Callie’s Review and Tips

It’s near impossible for me to not give five stars to any meal that tastes this good for so few calories. The versatility of this meal also amazes me. You get entirely different experiences whether you eat alone or as part of a larger meal. If you want to bulk it up, add in more orzo, and remember to add sufficient water when you do.

The recipe is easy to manipulate too. Add or remove vegetables to taste, and you can also adjust the spice level by altering the paprika.
