Soups & Stews
This Applebee's onion soup recipe delivers the same rich, cheesy comfort you crave from their menu—starting with layers of caramelized onions that melt into a velvety broth.
The secret lies in slow-cooking onions until they're deep golden and sweet, then finishing with a blanket of melted Gruyère that turns crispy on top. I've recreated this restaurant favorite at home, ensuring every spoonful delivers that perfect balance of savory, sweet, and umami.
The process is straightforward but requires patience—sautéing onions for 45 minutes until they're jammy and fragrant, then simmering in beef broth with herbs until deeply flavorful.
What sets this apart is the cheese topping: a mix of Gruyère and mozzarella that browns beautifully under the broiler, creating that signature crispy crust. This is the kind of soup that disappears faster than you can say "refill."
By the time you're done, you'll have a steaming bowl of onion soup with tender onions swimming in rich broth, topped with golden, crispy cheese that shatters at every bite.
The aroma alone will have everyone gathering around the table—it's that good. Serve with a side of garlic bread for the full restaurant experience.
Perfect for chilly evenings or when you need a hearty meal that feels like a hug in a bowl. The leftovers reheat beautifully, though I can't promise they'll last that long. Let's get cooking!
Ingredients for applebee's onion soup
Four large onions and a handful of pantry staples—this is how you recreate Applebee's iconic crispy cheese topping at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 4 large | Thinly sliced, about 4 cups total |
| Unsalted Butter 🧈 | 4 tbsp | Full-fat for best flavor |
| Beef Broth 💧 | 4 cups | Low-sodium preferred |
| Gruyère Cheese 🧀 | 1 cup | Freshly grated, sharp flavor |
| Mozzarella Cheese 🧀 | ½ cup | Shredded, low-moisture preferred |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Garlic Powder 🧄 | ½ tsp | Fresh garlic preferred if available |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For drizzling on top |
| Bread Crumbs 🍞 | ¼ cup | Optional for extra crunch |
The onions are non-negotiable here. Yellow onions work best for that sweet, jammy texture—red or white won't caramelize the same. Whole Foods or Trader Joe's carry the best quality, but any grocery store will do. Look for onions that feel heavy for their size and have crisp, dry skins. I usually buy a whole bag of 5 lbs and freeze extras—they keep for months. The key is patience: sauté them low and slow until they're deep golden, almost like jam. Don't rush this step, or you'll miss the magic.
No Gruyère? Parmesan or sharp cheddar works in a pinch, though the flavor won't be quite the same. The mozzarella should be low-moisture shredded—the kind in a can or block that you shred yourself. Pre-shredded gets clumpy and watery. For the broth, low-sodium is a must—you'll be adding plenty of salt later. Fresh thyme is ideal, but dried works fine at one-third the amount. If you're feeling fancy, add a splash of dry sherry or white wine when deglazing the pot—it adds depth that store-bought broth can't match.
This soup tastes even better the next day, so make a double batch if you can. Store it covered in the fridge for up to 5 days, or freeze portions for 3 months. When reheating, add a splash of water or broth to keep it from getting too thick. For serving, broil the cheese topping until it's golden and bubbly—3-4 minutes under the broiler—and finish with a drizzle of extra-virgin olive oil for extra richness. Leftovers? Just reheat and broil the cheese again—it's that good.

Step-by-step instructions for Applebee's onion soup recipe
Here's how to recreate that signature crispy Gruyère topping you love.
Cook the Onions Until Caramelized
Melt the 4 tbsp unsalted butter in a large Dutch oven over medium heat. Add the 4 large yellow onions that have been thinly sliced and spread them out evenly in the pan. You want them to sizzle gently without burning.
Cook the onions for 45-50 minutes, stirring occasionally, until they turn a deep golden brown color. This is where the magic happens—the onions should be soft, sweet, and caramelized with no raw edges remaining. If they start to stick, add a splash of water and scrape up any browned bits from the bottom of the pot. These bits are packed with flavor and will enrich your soup.
Build the Flavorful Broth Base
Once the onions are perfectly caramelized, sprinkle the 1 tbsp all-purpose flour over them and stir to coat evenly. Cook for 1-2 minutes until the flour turns a light golden color and the raw flour smell disappears. This step helps thicken the soup later.
Next, add the 4 cups beef broth, the 1 tsp dried thyme, 0.5 tsp garlic powder, 1 tsp salt, and 0.5 tsp black pepper. Stir everything together and bring the mixture to a gentle simmer. Let it cook uncovered for 15-20 minutes to allow the flavors to meld together. You'll know it's ready when the soup has a rich, aromatic smell and the onions are completely tender.
Prepare the Crispy Cheese Topping
While the soup simmers, create the signature crispy topping. In a small bowl, combine the 1 cup freshly grated Gruyère cheese, 0.5 cup shredded mozzarella cheese, and the 0.25 cup bread crumbs. Stir until the cheeses and bread crumbs are evenly mixed. This combination gives you the perfect balance of sharp, nutty Gruyère and mild mozzarella, with a satisfying crunch from the bread crumbs.
Spread the cheese mixture evenly over the top of the simmering soup. The heat from the soup will begin to melt the cheese, creating a bubbly, golden crust. This is the moment you've been waiting for—it's what makes this soup so special.
Broil for the Perfect Crispy Topping
Transfer the Dutch oven to the broiler and broil for 2-3 minutes. Watch carefully as the cheese melts and turns a beautiful golden brown color. You want it to be bubbly and crispy on top, with some areas that are slightly browned. If the cheese starts to brown too quickly, move the pot slightly away from the broiler element to prevent burning.
Once the cheese topping is perfectly crispy and golden, remove the soup from the broiler and let it cool for 1-2 minutes. This resting time allows the cheese to set slightly, making it easier to serve without losing all the crispy bits. Serve immediately with a drizzle of 1 tbsp extra-virgin olive oil on top for extra richness.
Pro Tips For Making Applebee'S Onion Soup
- Sweat the Onions Slow: I learned this the hard way—rushing the onions in butter turns them bitter. Cut them into even ¼-inch slices, then cook them over medium-low heat for at least 30 minutes, stirring occasionally. The goal is caramelized, translucent layers, not browned bits. (Yes, even if you’re impatient like me.)
- Use Two Cheeses, One Way: Gruyère melts like a dream, but mozzarella adds stretch. Shred the mozzarella separately—it’s the gooey glue holding everything together. Toss it in the last 2 minutes of broiling so it doesn’t turn rubbery. (Your future self will thank you.)
- Salt the Broth Early: Unsalted butter needs seasoning, and beef broth often doesn’t. Taste the broth before adding it to the pot—season it aggressively with salt and pepper now, not later. You can always dial it back, but you can’t fix blandness after the fact.
- Skip the Crowding: When topping with cheese, resist the urge to pile it all on at once. Spread it in an even layer—about ½ inch thick—so it browns evenly and doesn’t steam like sad, soggy nachos. A hot broiler (or broiler setting on your oven) guarantees a crispy crust in 3-5 minutes.
Best sauces and condiments for this dish
Gruyère-Cream Sauce
For a richer, creamier version of this soup, I make a quick Gruyère-cream sauce to stir into the finished broth. Melt 2 tbsp unsalted butter in a small saucepan, then whisk in ½ cup heavy cream and ½ cup freshly grated Gruyère.
Simmer for 3-4 minutes until the cheese melts completely, then stir into each bowl of soup. This adds a luxurious, velvety texture that feels like a restaurant-quality upgrade. 🧀
Garlic-Herb Oil
Drizzle the finished soup with garlic-herb oil for an extra layer of flavor. Heat ¼ cup extra-virgin olive oil with 2 minced garlic cloves, 1 tsp dried thyme, and a pinch of red pepper flakes until fragrant (1 minute).
Let cool slightly, then drizzle over the soup just before serving. The oil floats on top, adding a burst of aromatic garlic with every bite. 🌿
White Wine Deglaze
For a more sophisticated flavor profile, deglaze the pot with ¼ cup dry white wine after caramelizing the onions. Scrape up all the browned bits from the bottom of the pot, then add the wine and simmer for 2 minutes to cook off the alcohol.
This step adds depth and complexity that complements the rich broth beautifully. A Sauvignon Blanc or Chardonnay works perfectly. 🍷
Spicy Kick Option
If you love a little heat, stir in ½ tsp smoked paprika or ¼ tsp cayenne pepper when adding the broth. For a smoky-sweet contrast, top each bowl with a sprinkle of crushed red pepper flakes and a drizzle of hot honey.
The heat balances the richness of the cheese and onions wonderfully. 🌶️
Herb Garnish
Fresh herbs elevate this soup instantly. Sprinkle each serving with 1 tsp chopped fresh parsley or thyme leaves right before serving. For a pop of color, add a few edible flowers like nasturtiums or violets—they’re beautiful and add a mild peppery note.
Garnish with a pinch of flaky sea salt to enhance all the flavors. 🌱

Frequently asked questions
Can I use red onions instead of yellow onions for this recipe?
Yellow onions are ideal because they caramelize more deeply and develop that signature sweet, jammy flavor. Red onions will work, but they'll stay slightly sweeter and less rich. For the best restaurant-style results, stick with yellow onions—it's what makes this soup taste like Applebee's!
Why does my cheese topping keep getting rubbery instead of crispy?
Rubbery cheese usually means it didn't get hot enough or was broiled too long. For perfect crispiness, broil for 2-3 minutes on high heat, watching closely. Start with the rack in the middle position, then move it slightly lower if the cheese browns too quickly. A mix of Gruyère and mozzarella is key—Gruyère melts beautifully while mozzarella adds structure.
Can I make this soup ahead of time?
Make the soup base up to 2 days ahead and store it in the fridge. When ready to serve, reheat gently and top with fresh cheese, then broil just before serving. For the best texture, don't broil the cheese until the very end—it loses crispiness when reheated. Leftovers reheat beautifully for 3-4 days in the fridge.
What's the best way to serve this soup?
Serve in deep bowls with a side of garlic bread for the full restaurant experience. For extra flair, drizzle with garlic-herb oil or a splash of white wine (if you used it in cooking). The crispy cheese topping should be golden and bubbly—everyone will want seconds! Pair with a green salad or crusty bread to soak up the rich broth.
Can I substitute the beef broth with vegetable broth?
You can, but the flavor will be more mild and less savory. For a vegetarian version, use vegetable broth and add 1 tsp soy sauce or ½ tsp Worcestershire sauce (vegan version) to deepen the umami. The caramelized onions will still shine, but the broth won't have that rich, meaty depth. If you're committed to vegetarian, consider adding a splash of balsamic vinegar for complexity.
