A few days ago I asked my Instagram and Facebook communities what everyone would like to see more of on the blog this year. The responses were overwhelmingly along the lines of, “slow cooker, please!” I hear you!  When I made slow cooker Vegetarian Split Pea Soup a few weeks ago, I realized that I don’t utilize this amazing time saving appliance enough. So this week I made one of my family’s favorite soups, vegetarian minestrone, in the slow cooker. This hearty minestrone is perfect for busy nights when you still want to eat well. Soups are one of our favorite dinners because they are easy to fill with healthy ingredients like kid-friendly bite-sized vegetables and legumes. One of my favorite things about blogging is getting to help you find a way to eat well, even when life is crazy busy. This slow cooker minestrone is perfect for those no-time-to-cook nights and makes us feel so much better than fast food.

The kids said:

“I like this soup.”

“It tastes like pesto.”

This soup gets its wonderful Italian flavors of garlic and basil the easiest way possible – store bought pesto. It’s a little soup trick I learned from Ina Garten. As you’ll see in the short video, the hard vegetables get slowly cooked all day. Just before you’re ready to eat, the spinach, pasta, and beans get added just to warm up and wilt in. It will seem like you’re adding a ton of spinach, but watch how much it cooks down. Depending on my mood and what I have around the house, sometimes I use butternut squash and other times I use potatoes. My kids prefer the potatoes, but I love the sweetness the butternut squash ads.
