Cheesy Broccoli Cauliflower Soup

It’s getting cold outside, and you know what that means – it’s soup season! This Cheesy Broccoli Cauliflower Soup is full of simple, wholesome ingredients. It’s warm, cozy, and comforting. It’s cheesy. It also has loads of vegetables – but you don’t feel like you’re eating a healthy vegetable soup.

The broccoli, cauliflower, potatoes, carrots, and garlic are roasted in the oven to bring out a more smoky flavor and crunchy texture. The base is a combination of caramelized onions, garlic, vegetable broth, and sharp cheddar cheese.

We love adding plenty of garlic, and in this recipe, we used Pehoski Purple for its pungent, garlicky flavor. It becomes very earthy when roasted and sautéed, taking on a creamy buttery flavor. These attributes made it the perfect addition to this hearty winter soup. We also love to add extra garlic into our diet as it starts getting chillier out (and cold and flu season comes around) to take advantage of garlic’s anti-viral properties.

Our Italian Seasoning is also sprinkled in throughout the recipe, adding herbs like oregano and basil for an extra boost of flavor. It also contains plenty of our homegrown garlic as the first ingredient – yum!
