Soup is comfort food in the cold weather or if you are under the weather. It can be served as a vegetarian starter or be a full meal in itself. This instant pot orzo soup is loaded with vegetables. It makes a hearty meal in a matter of minutes.

Ingredients

This orzo pasta soup is loaded with veggies so you need a lot of veggies, you can use ones you have at hand but not limited to celery, carrots, spinach, corn kernels, onions, and green onions.

Also, you can use pasta of your choice instead of orzo. Tomato basil sauce can be substituted by tomato sauce or diced tomatoes.

Herbs like thyme, oregano, and rosemary, dried or fresh, add a great flavor to the soup. If you don't have them, you can skip them.

Since this is a vegan soup, I am using vegetable stock. Add some salt and pepper to your taste.

You will also need some olive oil, bay leaf, and garlic for sauteing.

Instructions

Vegetable pasta soup is one of the easiest recipes to make in the instant pot. First, turn the instant pot on saute mode on the normal setting.

Once hot, add some olive oil followed by bay leaf and garlic. Add the onions and continue to saute for about 30 seconds.

Add the other vegetables except for spinach and green onions. Add the tomato basil sauce, pasta, herbs, salt, pepper, and vegetable stock. Mix well and deglaze the bottom of the pot with a spatula.

Start the high pressure or manual mode for 0, yes zero, minutes. Once done, let the pressure lease naturally for 6 minutes and then release the remaining pressure.

Stir in the spinach and onion greens. Adjust salt, pepper, and herbs to taste.

I have used 3 qt. Instant Pot to make this recipe. A bigger batch can be made in the larger Instant Pot.

You can also make this recipe on the stovetop and cook the veggies, spices, and herbs in the vegetable stock until veggies are tender. Add cooked pasta towards the end and mix well.

Veggies: you can use vegetables of your choice. Zucchini, mushrooms, kale, and squash can be added to the soup.

Pasta: Instead of orzo, you can use small shell pasta or elbow macaroni.

Sauce: You can use marinara sauce and add more herbs.

Serving suggestions

Vegetable pasta soup is best when served hot. It can be enjoyed as a meal or an appetizer with breadsticks, French bread, or potato dinner rolls. You can serve it with crusty bread like sourdough bread. Garlic knots, pull-apart rolls, grilled cheese sandwich, and focaccia bread also go well.

Other side dishes like roasted potatoes, roasted sweet potatoes, or roasted broccoli also go well

Storage

You can refrigerate any leftover orzo soup for 2-3 days. When you are ready to server, you can reheat it in the microwave, stovetop or in the Instant Pot
