Preparation Instructions

This vegetarian sausage casserole is loaded with flavor and texture, and it’s easy to make with simple ingredients. Here’s how to prepare it:

chop onions and carrots

First, chop an onion and a carrot and heat some olive oil in a large pot over medium heat. Cook the onion and carrot until they are soft and tender, stirring occasionally.

Add garlic paste

Next, add some garlic paste and vegetarian Worcestershire sauce to the pot and cook for another minute, stirring well. This will add some depth and umami to the casserole.

allow to simmer

Then, pour in some vegetable broth and canned diced tomatoes, and season with smoked paprika, brown sugar, thyme, oregano, salt and pepper. Smoked paprika will give the casserole a nice smoky flavor, while brown sugar will balance out the acidity of the tomatoes. Thyme and oregano will add some herbal notes to the dish.

add bay leaf

Place a bay leaf on top of the mixture and bring it to a simmer. Then cover the pot with a lid and let it cook for 20 minutes. This will allow the flavors to meld and the sauce to thicken slightly.

add in cannellini beans

After 20 minutes, stir in some canned white beans and cooked vegetarian sausages. You can use any kind of vegetarian sausages you like, such as soy-based, seitan-based or mushroom-based. Cook the casserole uncovered for another 10 to 15 minutes, until the sausages are heated through and the sauce is bubbly.
