Ingredients Needed

Here’s what you’ll need to create the perfect garlic and onion soup:

6-8 large garlic cloves, minced or thinly sliced
2 large onions, thinly sliced (yellow or white onions work best)
4 cups vegetable or chicken broth (you can use low-sodium broth if you’re watching your salt intake)
2 tablespoons olive oil (extra virgin for richer flavor)
1 tablespoon butter (for a smoother, creamier texture)
1 teaspoon fresh thyme (or ½ teaspoon dried thyme)
1 bay leaf
Salt and pepper, to taste
1 tablespoon balsamic vinegar (optional, but it adds a nice depth of flavor)
A small baguette (for serving, optional but recommended)
Parmesan cheese (optional garnish)

Cooking Instructions

Prep the ingredients: Start by thinly slicing the garlic and onions. Set them aside. Mince the garlic finely to release more of its aroma. Prepare your broth by heating it slightly in a saucepan so it’s ready to pour in when needed.
Sauté the onions and garlic: In a large pot, heat the olive oil and butter over medium heat. Once the butter has melted and the oil is hot, add the onions. Cook, stirring frequently, until they become soft and golden brown. This should take about 15-20 minutes. Be patient here! The caramelization of the onions brings out their natural sweetness and adds depth to the soup.
Add garlic and seasonings: Once the onions are beautifully golden and sweet-smelling, add the minced garlic, thyme, and bay leaf. Stir everything together and cook for another 2-3 minutes until the garlic becomes fragrant but not burnt.
Pour in the broth: Add the broth to the pot, scraping up any delicious bits that might have stuck to the bottom of the pan. Bring the soup to a simmer and let it cook for about 20-30 minutes. This is when the flavors meld together beautifully.
Adjust the flavor: Taste the soup and adjust the seasoning with salt and pepper. If you like a bit of acidity to cut through the richness, stir in a splash of balsamic vinegar.
Serve: While the soup is simmering, slice up the baguette and toast the slices. Once the soup is ready, ladle it into bowls, add a slice or two of the toasted bread, and optionally top with freshly grated Parmesan cheese.
Enjoy!: Dive into your aromatic, soothing bowl of garlic and onion soup and savor each spoonful.

Ingredient Insights

Let’s take a deeper look at the star ingredients in this soup:

Garlic: This powerhouse ingredient is not only known for its pungent aroma and flavor but also for its many health benefits. Garlic is packed with antioxidants, has anti-inflammatory properties, and is believed to support heart health by lowering cholesterol levels. It’s also great for your immune system, especially during cold and flu season.
Onions: Like garlic, onions are part of the allium family, offering similar health benefits. They contain sulfur compounds and antioxidants that support immune health. Onions are also rich in fiber, which aids digestion. Yellow onions, in particular, are perfect for this soup because their sweetness develops beautifully when caramelized.
Broth: The choice of broth (vegetable or chicken) is essential for enhancing the base flavor of the soup. Using a homemade broth or a high-quality store-bought option will make a noticeable difference in taste. Broth is the liquid backbone of this soup, and it should complement the rich flavors of the garlic and onions.
Balsamic Vinegar: Though optional, balsamic vinegar brings a gentle sweetness and acidity that elevates the soup’s flavor. The slight tanginess helps balance the richness of the caramelized onions and adds complexity to the final dish.

Expert Tips

To take this garlic and onion soup to the next level, consider these expert tips:

Slow and Steady Wins the Race: When caramelizing the onions, don’t rush it. Low and slow is key. If you turn the heat too high, the onions may burn instead of caramelizing, which will introduce a bitter taste to the soup.
Customize the Broth: If you’re looking for a richer flavor, opt for a bone broth. The extra collagen will make the soup even more nourishing. For a vegetarian option, vegetable broth works perfectly.
Use Fresh Herbs: While dried thyme works, fresh thyme really takes the soup to the next level. The fresh herbs release a lovely fragrance as they cook, adding a layer of complexity to the dish.
Make It a Meal: Want to make this soup more substantial? Add some sautéed mushrooms, spinach, or kale to the soup for added texture and flavor. For a heartier dish, you can also add cooked white beans or lentils.

Recipe Variations

Vegan Version: Swap the butter for an extra tablespoon of olive oil, and use vegetable broth for a completely plant-based soup. You can also omit the Parmesan cheese or use a vegan cheese alternative.
Cheesy Garlic and Onion Soup: Add a bit of shredded Gruyère or Swiss cheese to the soup right at the end, allowing it to melt and create a creamy, cheesy texture.
Spicy Twist: Add a pinch of red pepper flakes when you sauté the garlic and onions for a slight kick. You can also stir in a bit of hot sauce or fresh chopped chili peppers.
Caramelized Onion and Garlic Toast: For an extra indulgent treat, make garlic bread with caramelized onions. Top the toasted baguette slices with this mixture, bake in the oven for a few minutes, and place it on top of your soup for an extra layer of flavor.

Final Words

This garlic and onion soup is simple yet incredibly satisfying. The combination of slow-cooked onions, fragrant garlic, and rich broth creates a deeply flavorful base that is both comforting and invigorating. It’s a dish that reminds us that great meals don’t need to be complicated; sometimes, the most straightforward ingredients can deliver the most memorable results.
