How to Make Rustic French Roasted Garlic Soup with Caramelized Onions Recipe
Step 1: Roast the Garlic
Begin by preheating your oven to 375°F (190°C). Prepare the garlic heads by slicing off their tops to expose the cloves, drizzle generously with olive oil, and wrap tightly in foil. Roasting them for 35 to 40 minutes transforms their sharpness into heavenly sweetness, yielding golden, tender cloves that melt into the soup beautifully.
Step 2: Caramelize the Onions
While the garlic roasts, heat olive oil and butter in a pot over medium heat. Add the onions and cook slowly, stirring occasionally, until they turn a deep golden brown, releasing their natural sugars. This process takes about 15 to 20 minutes but patience pays off with that luscious sweetness critical to this rustic soup.
Step 3: Combine Flavors
Once the garlic and onions are ready, mash the soft garlic cloves into the pot with the onions. Add thyme, bay leaf, salt, and pepper. Stir everything together to marry the flavors before adding your vegetable broth to the mix.
Step 4: Simmer the Soup
Bring the mixture to a gentle boil then reduce the heat and let it simmer uncovered for 15 to 20 minutes. This simmering stage allows all the components to meld and deepen in flavor while achieving the perfect balance of savory and sweet.
Step 5: Blend and Finish
Carefully blend the soup to your preferred consistency—whether silky smooth or slightly rustic with small bits for texture. Stir in the milk or cream gently, warming the soup without bringing it back to a boil, which keeps that delicate creaminess intact.
How to Serve Rustic French Roasted Garlic Soup with Caramelized Onions Recipe
Garnishes
A simple sprinkle of freshly cracked black pepper and chopped parsley is all you need to elevate this soup visually and flavorwise. These garnishes add a fresh brightness that complements the deep, roasted notes beautifully.
Side Dishes
Serve your soup alongside warm, crusty bread to soak up every last drop. A side of mixed green salad or a light French baguette pairs wonderfully, making the meal feel complete and extra satisfying.
Creative Ways to Present
For a cozy dinner party vibe, serve the soup in rustic bowls with a drizzle of fragrant olive oil on top. Or sprinkle some toasted nuts or crispy shallots for added crunch and flair. A touch of grated cheese like Parmesan or a swirl of herb-infused oil can also make this humble soup feel extraordinary.
Make Ahead and Storage
Storing Leftovers
This soup is one of those dishes that tastes even better the next day as the flavors have more time to develop. Store leftovers in an airtight container in the fridge for up to 3 days without losing its deliciousness.
Freezing
If you want to keep it longer, freeze the soup—but omit the dairy before freezing for best results. Frozen in a suitable container, the soup will keep well for up to 3 months, making it perfect for a future cozy night in.
Reheating
Reheat gently on the stovetop over low heat to prevent the milk or cream from curdling. Stir frequently to warm the soup evenly and preserve its silky texture. Add a little extra cream or milk if it seems thick after refrigeration.
FAQs
Can I use garlic powder instead of roasted garlic?
While garlic powder adds a quick punch of flavor, roasted garlic has a unique sweetness and softness that powder just can’t replicate. For this Rustic French Roasted Garlic Soup with Caramelized Onions Recipe, roasting whole garlic heads is worth the extra step for that rich depth.
Is it possible to make this soup vegan?
Absolutely! Swap the butter for a plant-based option and use oat or almond milk instead of cream. The roasted garlic and caramelized onions provide so much natural flavor that it stays deliciously comforting even without dairy.
Can I prepare the soup base in advance?
Yes, you can roast the garlic and caramelize the onions a day ahead, storing them separately in the fridge. When ready, combine and finish the soup with broth and cream. This makes weeknight prep quick and easy.
What can I add for extra depth in flavor?
Feel free to toss in a splash of white wine during caramelization or add a Parmesan rind to the broth for an umami boost. Just remember to remove the rind before blending.
How thick should the soup be?
That’s totally up to your preference! Some like it velvety smooth and creamy, others enjoy a bit more texture with small pieces of onion and garlic. Blending to your desired consistency personalizes this Rustic French Roasted Garlic Soup with Caramelized Onions Recipe perfectly.

Instructions
- Roast Garlic: Preheat your oven to 375°F (190°C). Slice off the tops of the garlic heads, drizzle them with olive oil, then wrap in foil. Roast in the oven for 35-40 minutes until the cloves are golden and tender, developing a rich depth of flavor.
