We all have days when we decide what to make based on what’s in the fridge that needs using up, right? That’s how we came to create this delicious green bean soup with caramelized onions and mushrooms.

We have a garden, and love growing green beans. In fact, our green bean plants are always our most prolific crop, so when harvest time comes around, we’re always looking for creative ways to enjoy green beans.

You can use fresh or frozen green beans for this recipe.

Caramelize Extra

Whenever you caramelize onions and/or mushrooms, you may also want to cook more than you need and use them for other dishes. There are many uses for caramelized onions and mushrooms.

We almost always double the amount called for so as to have extra on hand is a good “planned over” strategy. You can use caramelized toppings for burgers and omelettes, and for other soups like this daikon noodle soup with caramelized onions and portobello mushrooms.

Just keep in mind that the raw veggies will cook down to only about 25% of their original measurement through the caramelization process, so plan accordingly.
