Introduction
Picture this: it’s the middle of winter, your windows are fogged up, you’re curled on the couch with a blanket that’s definitely seen better days, and your stomach is practically yelling at you for something cozy. That’s exactly how I stumbled back into French onion soup. Honestly, I didn’t even plan to make it that night—I was just staring into my fridge wondering how the heck I ended up with so many onions (thank you, overzealous grocery shopping brain). But once that first whiff of onions sizzling in butter hit my kitchen, I knew I was in for one of those easy weeknight dinners that somehow feels like a fancy night out in Paris.
Here’s the thing: French onion soup isn’t fast food. Nope, it’s a slow build, like waiting for your favorite TV drama to finally spill the tea. Caramelizing onions takes time, and I’ve learned the hard way that you cannot rush it. (Ask me about the time I turned my onions into sad, burnt crisps while scrolling Pinterest for best meal prep plans—oops.) But that patient, golden, deeply sweet transformation? Worth every single minute.
And can we talk about the toppings? Toasted baguette slices that crunch under your spoon, gooey blankets of melted Gruyère and comté cheese stretching with every bite, and that broth—rich, savory, and layered with flavors that feel like they’ve been simmering for centuries. Honestly, it’s the definition of healthy comfort food. It warms you up from the inside out, like wrapping yourself in a cozy sweater you forgot you had in the closet.
This soup has also become one of my favorite budget-friendly recipes. Onions? Cheap. Bread? Basically pocket change. Cheese? Okay, cheese is where you’ll spend a little, but let me tell you: do not skimp. The right cheese makes this soup feel like the best high protein frozen meals you could never actually buy at the store because nothing compares to the real deal. And if you’re into meal planning chicken or low calorie chicken meal prep, this soup works as a starter that makes even the simplest grilled chicken dinner feel like a full-on French feast.
Why You’ll Love This Recipe
- Cozy Factor on Max – This soup feels like a hug in a bowl. Truly. One spoonful and suddenly winter doesn’t feel so bad.
- Restaurant-Style at Home – Forget overpriced bistro bowls; this is better, and you don’t even have to put on real pants.
- Perfect for Leftovers – The broth actually gets deeper and richer the next day. Just toast fresh bread, melt cheese, and boom—round two of happiness.
- Beginner-Friendly – Don’t let the caramelization scare you. If I can do it without burning my kitchen down (again), you can too.
- Meal Prep Win – Soup keeps beautifully in the fridge and freezer, so think of it as your own stash of ready made protein meals for the week.
What Makes This Recipe Special?
For me, it’s all about the layering of flavors. Every step is simple, but they add up like puzzle pieces. Slowly caramelized onions bring sweetness, the splash of brandy or vermouth adds depth, a good beef stock creates the foundation, and then there’s the crown jewel: that golden cheese crust. It’s messy, it’s gooey, it’s everything. And let’s be real, scraping melted cheese off the side of the bowl might be the best part.
Also, this soup is secretly one of the best quick family meals. It looks elegant but it’s really just bread, onions, and cheese dressed up with some broth. I mean, come on—tell me that isn’t the definition of sneaky brilliance.
Ingredients
Alright, let’s dig into what you’ll need, because while French onion soup feels fancy, the ingredient list is mostly kitchen staples.
- Yellow Onions – These are your MVP. Slice them thin and let them do their sweet, slow magic. You can mix in a sweet onion or two for extra flavor.
- Butter + Olive Oil – Double the fat, double the flavor. Butter for richness, oil to prevent burning. Trust me, you want both.
- Garlic – Freshly minced. Don’t even think about using garlic powder here.
- Brandy + Dry White Wine – These aren’t just fancy add-ins; they deglaze the pot and add layers of flavor. If you skip them, replace with beef stock, but you’ll miss that extra oomph.
- Fresh Thyme + Bay Leaf – These herbs quietly sit in the broth, infusing everything with cozy vibes, then bow out gracefully before serving.
- Worcestershire Sauce + Fish Sauce – Flavor boosters. They don’t taste “saucy” on their own but add serious depth.
- Beef Stock – The backbone of the whole dish. Make sure it’s good quality. If it tastes flat on its own, it won’t save your soup.
- Salt + Pepper – Freshly cracked pepper is a must. Don’t be shy with the seasoning.
- French Baguette – Day-old bread works perfectly here. You want those crisp edges.
- Gruyère + Comté Cheese – The ultimate melty duo. Nutty, creamy, golden-brown perfection.
Pro tip: whatever you do, don’t use pre-shredded cheese. It has that weird anti-caking powder that messes up the melt. Been there, regretted that.
How to Make It Step-by-Step
Okay, apron on, deep breath—here’s how I make mine.
- Slice the Onions
I halve them, then cut into thin strips. My first mistake ever was cutting them chunky. Big mistake. You want thin slices so they caramelize evenly. - Caramelize (Patience Required)
Butter and olive oil go into the pot, then the onions. I stir every few minutes while blasting some music so I don’t lose my mind waiting. Around 30 minutes in, they look golden. At 60 minutes, they’re jammy and deep brown. Once, I thought “Eh, close enough” at 25 minutes. Don’t. They tasted raw and sharp. Learn from me. - Add Garlic and Deglaze
Toss in garlic, let it get fragrant. Then splash in the brandy and wine. Scrape up those browned bits—this is where flavor hides. I once forgot to scrape, and the bottom basically became onion cement. Oops. - Broth & Seasoning
Stir in flour, then pour in beef stock, herbs, Worcestershire, and fish sauce. Let it simmer. Your kitchen now smells like the coziest French café. - Toast the Bread
While soup simmers, slice your baguette, drizzle with olive oil, and toast until crisp. Rub each slice with raw garlic after. That little move? Game-changer. - Assembly Time
Ladle soup into oven-safe bowls, top with toast, then pile on cheese. Be generous. Broil until bubbly and golden. Warning: the cheese will tempt you to dig in instantly. Resist. It’s basically molten lava at this stage.
Tips for Best Results
- Don’t rush the onions. They need at least an hour.
- Taste your stock before committing. Bad stock = bad soup.
- Use oven-safe bowls. I once melted a not-oven-proof dish. RIP favorite bowl.
- Fresh thyme > dried thyme here.
Ingredient Substitutions & Variations
- Vegetarian – Use veggie broth, skip Worcestershire and fish sauce.
- Vegan – Olive oil instead of butter, dairy-free cheese.
- Cheese Swap – Mozzarella, gouda, or fontina work if you can’t find Gruyère.
- Bread Twist – Try sourdough slices instead of baguette.
Serving Suggestions
Serve this with a crisp green salad, roasted veggies, or mashed potatoes. Honestly, it also pairs ridiculously well with a grilled cheese sandwich (cheese on cheese, why not?). Add a glass of sparkling water or lemonade, and you’ve got the ultimate cozy night meal. Or, if you’re going full comfort, soup + Netflix + sweatpants = perfection.
Pairing Ideas (Drinks, Sides, etc.)
- Drinks: sparkling water, apple cider, or herbal tea.
- Sides: light salad, roasted asparagus, or mashed potatoes.
- Dessert: something simple like chocolate mousse or a scoop of ice cream.
How to Store and Reheat Leftovers
Store soup (without bread) in an airtight container up to 4 days. Reheat gently on the stove, not the microwave—it messes with the texture. Toast bread fresh each time for crunch.
Make-Ahead and Freezer Tips
Make the broth and onions ahead, freeze in containers for up to 3 months. Add fresh bread and cheese when ready to serve.
Common Mistakes to Avoid
- Cutting onions too thick.
- Rushing caramelization.
- Using pre-shredded cheese.
- Forgetting oven-safe bowls (learned that one the hard way).

Easy French Onion Soup (No Alcohol)
Ingredients
- 2 tablespoons extra-virgin olive oil, plus more for brushing bread
- 2 1/2 tablespoons unsalted butter
- 2 pounds yellow onions, halved and thinly sliced (about 1/4-inch thick)
- 1/2 pound sweet onion, halved and thinly sliced
- 1 1/2 tablespoons fresh garlic, minced (about 4 to 5 cloves)
- 6 sprigs fresh thyme, plus more for optional garnish
- 1 large bay leaf
- 1/4 cup low-sodium beef stock (for deglazing; replaces brandy)
- 1 cup low-sodium beef stock (replaces dry white wine/vermouth)
- 1 tablespoon apple cider vinegar (split use; for deglazing and brightness)
- 5 1/2 cups low-sodium beef stock (main soup base)
- 2 1/2 teaspoons Worcestershire sauce
- 2 1/2 teaspoons fish sauce
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper, plus more to taste
- 1/2 baguette cut into 1/2-inch slices
- 1 large garlic clove, halved (for rubbing toast)
- 1 cup Gruyère cheese, freshly shredded
- 1/2 cup Comté cheese, freshly grated
- Chives or extra thyme leaves, finely chopped (optional garnish)
Instructions
- Warm the olive oil and butter in a large Dutch oven over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring every few minutes, until the onions slowly turn golden and jammy, 50–70 minutes. If the pot looks dry or onions start to brown too fast, lower the heat and add 1–2 teaspoons water to loosen.
- When onions are a deep caramel brown, clear a small spot on the bottom of the pot and add the minced garlic. Cook until fragrant, about 30–60 seconds, stirring to combine.
- Deglaze: Pour in 1/4 cup beef stock and 1–2 teaspoons apple cider vinegar. Scrape up the browned bits (fond) from the pot with a wooden spoon until the bottom is clean and the liquid mostly reduces, 1–2 minutes.
- Build the broth: Stir in the additional 1 cup beef stock, the 5 1/2 cups beef stock, thyme sprigs, bay leaf, Worcestershire sauce, fish sauce, black pepper, and the remaining vinegar if desired for brightness. Bring to a boil, then reduce to a gentle simmer. Partially cover and cook 25–30 minutes, stirring occasionally. Taste and adjust salt and pepper.
- Toast the bread: While the soup simmers, heat the oven to 400°F (204°C). Brush baguette slices lightly with olive oil on both sides, place on a baking sheet, and toast 5–8 minutes until crisp and lightly golden. Rub one side of each toast with the cut side of the garlic clove.
- Cheese topping: Switch oven to BROIL. Set oven-safe bowls on a baking sheet. Ladle hot soup into bowls, top each with 1–2 toasts, and cover generously with the Gruyère and Comté.
- Broil 3–5 minutes until the cheese is fully melted, bubbling, and spotty golden brown. Carefully remove. Discard thyme sprigs and bay leaf if visible, garnish with chopped chives or thyme if using, and serve hot.
