Easy Healthy Soup

We love a vegetable soup but this garlic onion soup recipe has a deeper flavor and is very simple to make. It’s a wonderful soup to have when you’re feeling under the weather, all thanks to the garlic which is slowly simmered to create a sweet caramelized flavor.

  • Meal Prep It! This soup is perfect to make a large batch of and serve for lunch throughout the week.
  • Use a large can of diced tomatoes to save time. Just dump right in along with juices.
  • A whole garlic bulb is used to create the recipe, which is about 10 garlic cloves. Garlic can help boost our immune function making it great to help fight off a cold.
  • The soup is sweet, tangy and full of dried herbs – one of my favorite kinds of recipes!
  • Leftovers also work great as a homemade spaghetti sauce!
Ingredients to make recipe including bowl of chopped onion, can of diced tomato, bowl of garlic cloves, small bowls of herbs, and bowl with broth.

Recipe Ingredients

GARLIC: This soup is made with a whole garlic bulb, which is 10 garlic cloves. It seems like a lot, but the garlic is slowly simmered to help it caramelize and create a sweet flavor where you won’t notice the garlic taste.

ONION: Two small yellow onions are diced to create 3 cups worth. You can also use white onions or red onions, depending on what you have available.

TOMATOES: The soup uses a large (28 oz) can of diced tomatoes. Choose a can without any added herbs as there is plenty being added to the recipe already.

SEASONINGS: The soup is made with a combination of thyme, parsley, salt and pepper. It’s simple but adds a really lovely flavor.

Recipe Tips

  • Garlic and onion should simmer for a full 20 minutes to get the best flavor.
  • To prevent burning, reduce heat to a low-medium temperature (less than “medium”) so that onions cook very slowly during this step.
  • To save time, use a garlic mincer to puree the garlic.
  • You only need 2 cups of broth for this recipe. Freeze the leftover broth in an ice cube tray for future soup recipes!
  • Soup leftovers will thicken slightly. This makes them great to use as a flavorful pasta sauce. Just reheat in the microwave and serve on top of fresh pasta.
