Ingredients for applebee's baked french onion soup
These twelve ingredients transform into Applebee's signature crispy, cheesy French onion soup.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 5 whole | Yellow or sweet onions preferred |
| Beef Broth 🍲 | 6 cups | Homemade or high-quality store-bought |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening broth |
| Unsalted Butter 🧈 | 4 tbsp | European-style preferred |
| Gruyère Cheese 🧀 | 2 cups | Freshly grated, high-quality |
| Baguette 🍞 | 1 whole | Stale or lightly toasted |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth of flavor |
| Fresh Thyme 🌿 | 1 tbsp | Chopped, or dried at 1/3 amount |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Worcestershire Sauce 🍶 | 1 tbsp | For umami depth |
| Olive Oil 🫒 | 1 tbsp | For bread toasting |
The onions are the heart of this soup—5 whole yellow onions is the magic number for that signature sweetness. Costco or Trader Joe's usually have them in bulk, but any grocery store will do. Look for onions that feel heavy for their size and have crisp, dry skins. The Gruyère is non-negotiable for that authentic restaurant flavor—Whole Foods or specialty cheese shops carry the good stuff. If you can't find Gruyère, Comté or Emmental work in a pinch, but the flavor won't be quite the same. For the beef broth, I always opt for homemade or high-quality store-bought like Pacific Foods—the canned stuff just doesn't have the same depth.
No fresh thyme? Dried works at one-third the amount, but trust me on the fresh stuff if you've got it. The Worcestershire sauce adds that umami kick—Lea & Perrins is the gold standard. Running low on Gruyère? Parmesan mixed with a little mozzarella can mimic some of the texture. The baguette should be stale or lightly toasted—Trader Joe's sells perfect pre-sliced baguettes that work great. For the butter, European-style like Plugrá melts beautifully and adds richness. If you're short on time, olive oil butter substitutes work, but you'll lose that creamy texture. The flour is just for thickening—don't skip it, or your soup will be too thin.
This soup tastes even better the next day—4-5 days in the fridge, honestly. For the crispy cheese top, broil for 2-3 minutes right before serving. The bread stays crispy for about 10 minutes after baking, so have your bowls ready. Freeze portions without the cheese top—just add it fresh when reheating. The caramelized onions keep for 5 days in the fridge, so make extra if you're planning to use them elsewhere.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe because it’s actually one-pot—no extra bowls, no fuss. Just caramelize those onions in butter, stir in flour and broth, and boom: you’re halfway there. The Gruyère melts right into the broth, so you don’t even need to pre-shred it (I just tear it with my hands—no fancy tools).
- Caramelized Gold: That slow cook of onions until they’re deep amber? Chef’s kiss. The beef broth deepens into something rich and savory, while the Gruyère adds a nutty, melty finish that feels fancy but takes zero effort. Honestly, the first time I made it, I nearly skipped dinner just to eat the pan.
- Weeknight Crowd-Pleaser: This feeds four easily, but I’ve also doubled it for six without breaking a sweat. It’s the kind of dish that makes people sigh with happiness—great for date nights, game days, or when your partner’s friend “just dropped by.” (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suck: Most baked soups turn into sad, watery messes the next day, but not this one. The crust stays crispy, the broth stays rich, and I’ve reheated it three times without complaint. Plus, it’s cheap—onions and broth stretch forever, and Gruyère isn’t as pricey as you’d think if you buy it in blocks. My budget and my taste buds thank me.
Step-by-step instructions for French onion soup with Applebee's-style crispy cheese crowns
Here's how to recreate that signature restaurant experience at home—silky caramelized onions, rich beef broth, and golden Gruyère cheese crowns.
Caramelize the Onions to Perfection
Peel and slice the 5 whole yellow onions into thin half-moons—about ⅛-inch thick. Melt 2 tablespoons of the unsalted butter in a large Dutch oven over medium-low heat. Add the onions and cook for 30 minutes, stirring occasionally, until they soften and release their moisture.
Here's the thing—this is where patience pays off. After 30 minutes, reduce heat to low and continue cooking for another 45-60 minutes, stirring every 10 minutes. You're looking for deep golden brown caramelization—the onions should be soft, sweet, and jam-like with a rich color. If they stick, add a splash of beef broth to loosen them. The longer they cook, the more complex the flavor becomes.
Build the Rich Broth Base
Once the onions are caramelized, increase heat to medium and add the remaining 2 tablespoons unsalted butter. Stir for 1 minute until melted, then sprinkle in the 2 tablespoons all-purpose flour and cook for 2 minutes, stirring constantly to create a roux. This will thicken your broth beautifully.
Gradually whisk in the 6 cups beef broth, 1 tablespoon Worcestershire sauce, and 1 tablespoon minced garlic cloves. Bring to a gentle simmer and cook for 10 minutes to let the flavors meld. Season with 1.5 teaspoons salt and 0.5 teaspoon black pepper, then stir in the 1 tablespoon chopped fresh thyme. Taste and adjust seasoning—this broth should be rich and savory, with just a hint of sweetness from the caramelized onions.
Toast the Baguette Slices
While the soup simmers, preheat your broiler to high. Cut the whole baguette into 16 slices (about ½-inch thick). Brush both sides of each slice with 1 tablespoon olive oil and arrange them on a baking sheet. Toast for 3-4 minutes until golden brown and crispy—this gives that perfect crunch you crave.
Here's a pro tip: If your baguette is fresh, toast it longer to remove excess moisture. For stale bread, just 2 minutes will crisp it up nicely. The slices should be firm enough to hold their shape when topped with cheese later.
Assemble and Bake to Crispy Perfection
Preheat your oven to 400°F. Ladle the onion soup into 4 oven-safe bowls (about 1½ cups per bowl). Top each with 4 toasted baguette slices, slightly overlapping them to create a base. Spoon about ½ cup of the gruyère cheese over each slice, making sure it covers the bread completely.
Watch for that moment when the cheese starts to bubble and turn golden—this is when you know it's ready. Bake for 3-5 minutes until the cheese is deeply golden brown and bubbly. The edges should be crispy, with a beautiful caramelized crust. For extra crispiness, broil for 1-2 minutes at the end, keeping a close eye to avoid burning.
Serve Immediately with Fresh Herbs
Remove from the oven and let sit for 1 minute to allow the cheese to set slightly. Garnish each bowl with extra chopped fresh thyme and a sprinkle of black pepper. Serve immediately—this soup is best enjoyed while the cheese is still bubbly and the bread is crispy.
Here's the secret to that Applebee's-style experience: The contrast between the silky, rich onion soup and the crispy, golden cheese crowns is what makes this dish unforgettable. Each bite delivers layers of caramelized sweetness, savory broth, and that perfect crunch from the toasted baguette and melted cheese. Enjoy it straight from the oven for the ultimate comfort food experience!
Pro Tips For Making Applebee'S Baked French Onion Soup
- Caramelize the Onions Low and Slow: I learned this the hard way—rushing the onions with high heat turns them bitter. Simmer them in butter at medium-low for 45-60 minutes until deep golden and jammy. The soup’s depth comes from this step, not just the cheese.
- Use Cold Butter for Roux: Skip the melted butter—toss cold cubed butter into the flour to make a roux that won’t scorch. Pulse it briefly in a food processor for a smoother texture, then whisk it into the broth. This avoids that burnt flour taste that ruins the whole dish.
- Don’t Skip the Broth Reduction: The recipe might not say it, but reducing the beef broth by 25% before adding the roux thickens the soup properly. It also concentrates the flavor—just simmer uncovered until slightly syrupy. (Yes, even if you’re impatient like me.)
- Toast the Cheese Before Melting: Sprinkle Gruyère over the soup before broiling, then hit it with a kitchen torch or broiler for 2-3 minutes. The direct heat makes it crispy and golden instead of just soft. If you don’t have a torch, broil on high for 1-2 minutes—watch it like a hawk.
Make-ahead tips for leftovers
Prep Ahead Essentials
The caramelized onions are the star of this soup, and they keep beautifully for 5 days in an airtight container in the fridge. Make them first—this is the most time-consuming step—and store them in the fridge until you're ready to assemble.
I like to freeze half the batch in 2-cup portions for quick future meals. 🧅
Broth Prep Strategy
Make the broth base up to 2 days ahead and store it in the fridge. The flavors deepen over time, and you can reheat it gently on the stovetop before adding the caramelized onions.
If using store-bought broth, opt for Pacific Foods or Swanson Premium brands—they have better flavor than generic options.
Bread Prep Shortcut
Toast your baguette slices 1 day ahead and store them in a sealed container at room temperature. They'll stay crispy for up to 24 hours, making assembly day a breeze. For extra crispiness, toast them again for 1-2 minutes before adding cheese. 🍞
Cheese Storage Hack
Grated Gruyère loses its sharpness over time, so grate it fresh when ready to assemble. If you must prep ahead, store the whole block in the fridge and grate just before baking. For a shortcut, use pre-shredded Gruyère (like Kraft brand), though it won't be as flavorful.
Complete Assembly Timeline
On serving day, reheat the broth with caramelized onions for 10 minutes, then assemble bowls and bake immediately. The cheese should go on fresh from the fridge—pre-melting it will make the crust less crispy.
For a crowd, assemble bowls 30 minutes ahead and reheat covered at 350°F for 10 minutes before broiling.
Freezer-Friendly Option
Freeze the soup (without cheese) in quart-sized freezer bags for up to 3 months. Thaw overnight in the fridge, then reheat on the stove. Add fresh toasted bread and cheese when ready to bake—this keeps the texture perfect. Just add 1-2 tbsp water when reheating to restore richness. ❄️

Frequently asked questions
Why does Applebee's French onion soup have such a crispy cheese top?
The secret lies in the toasted baguette base and fresh Gruyère cheese. The bread gets crisped in the broiler first, then topped with cold cheese that melts dramatically in the oven. Using freshly grated Gruyère (not pre-shredded) creates a tighter crust that browns beautifully. The key is baking at 400°F until the edges are golden and bubbly.
Can I make this soup without a Dutch oven?
Use a large heavy-bottomed pot or even a deep skillet. The caramelization will take slightly longer, but the technique remains the same. Just stir more frequently to prevent burning. For the baking step, any oven-safe dish that fits your bowls will work—even a baking sheet lined with parchment.
What's the best cheese substitute if I can't find Gruyère?
For authenticity, use a mix of Comté and Emmental (50/50 ratio). If you're short on time, sharp white cheddar plus a little mozzarella works surprisingly well. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper browning. The cheese should melt into a golden, bubbly crust, not a greasy layer.
How do I fix soup that's too thin after baking?
If the soup seems watery after baking, it likely didn't thicken enough during the roux step. Mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir into the soup, and simmer for 2-3 minutes until thickened. For future batches, cook the roux for 3-4 minutes (not just 2) to ensure proper thickening.
Can I make this soup vegetarian?
Yes! Replace the beef broth with vegetable broth and add 1 cup red wine to the caramelized onions for depth. Use vegetarian Worcestershire sauce and consider adding 1 cup mushrooms sautéed with the onions. The flavor will be different but still delicious—just expect a lighter, more herb-forward taste.
