Slow Cooker Spanish Potato Onion Soup

A simple soup of potatoes, onions and Spanish-influenced seasonings for the slow cooker, perfect for cold weather. Adapted from Moosewood Restaurant Cooks at Home: Fast and Easy Recipes for Any Day, where it’s written as a stovetop recipe. I opted to toss everything in the slow cooker instead.

A few hours later we were rewarded with this hearty and delicious soup ready and waiting for us at the end of a long day. Served with crusty bread and a green salad, it made for a satisfying meal.

Including more soups in our diet has been one of my tricks for easy healthy weight loss. They’re an easy delicious way to increase your intake of vegetables, filling you up with fewer calories.

As Mireille Guiliano says in her wonderful book, French Women Don’t Get Fat, “The evening soup eater tends to consume less fat and less food overall, feeling satiated through the night, after which she needs “a real meal” on rising to get her through the morning.”

And with leftover soup in the fridge, you’ve got a low PointsPlus value solution ready and waiting whenever hunger strikes.

    I made the Spanish onion potato soup tonight and must thank you for a wonderful recipe. The spices are right on. I used the stove top to cook it and let the onions cook up bit before adding everything else. had to add garlic as well. Well balanced and with bread just delicious.
