Those onions are the soul of this soup. Yellow onions work best—they caramelize beautifully. Grab the biggest, freshest ones you can find, preferably from the produce section at Whole Foods or your local farmers market. The key is patience: 45 minutes minimum of slow cooking until they're deep golden and sweet. Skip the pre-chopped onions—they brown too fast. For extra flavor, add a pinch of sugar if your onions aren't sweet enough naturally. The butter? Use unsalted—you'll be adding salt later, and you want to control the flavor.
No Gruyère? Swiss or sharp cheddar works in a pinch, but you'll lose that signature nutty depth. Emmental is harder to find—Gruyère alone can work if you double the amount. Fresh bread is non-negotiable for those crispy crowns, but stale bread from the day before actually crisps up better. Celery crowns need that flour coating—Panko works too if you're in a hurry. The thyme can be dried, but fresh is ideal. For the beef broth, low-sodium is crucial—you don't want to over-salt your soup. And if you're feeling fancy, add those minced garlic cloves when caramelizing the onions—they'll mellow out perfectly.
This soup tastes even better the next day. Store the unbaked version in the fridge for up to 3 days—just bake from cold. For the crispy celery crowns, prep them ahead and store in an airtight container for 1 day before baking. The bread slices keep well too—wrap in foil and refrigerate for up to 2 days. Freeze the soup base (without cheese) for 3 months
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe because it’s that simple—just onions, butter, broth, and cheese. No chopping mountains of veggies or layering a dozen ingredients. You caramelize those onions until they’re sweet and jammy, then melt cheese right on top. The pan does most of the work while you sip wine and pretend you’re a chef.
- Cheese Pull Heaven: Here’s what sold me—the way the Gruyère and Emmental stretch and crisp into golden blankets when torched. That crispy edge with the creamy center? It’s the kind of bite that makes you close your eyes and groan. Plus, the beef broth adds depth without overpowering the rich, melty cheese.
- Weeknight or Weekend: Between us, this soup is my go-to for lazy Fridays or when unexpected company shows up. Serve it with crusty bread for a no-fuss dinner, or turn it into a casserole for a potluck. Honestly, it’s equally happy as a quick weeknight meal or a fancy-ish weekend treat.
- Budget-Friendly Leftovers: A single batch stretches for days—perfect for when you’re not sure what you’ll crave tomorrow. The onions caramelize even better the next day, and the cheese stays gooey. I’ll be real: I’ve reheated this for breakfast with toast, and no one judged me. (Okay, fine, my husband did, but he’s a snob.)
Step-by-step instructions for Applebee's onion soup with crispy celery crowns
Here's how to recreate Applebee's signature crispy-topped onion soup at home—rich, cheesy, and topped with golden bread magic.
🍳 Step 1: Caramelize the Onions to Perfection
Heat the 0.5 cup unsalted butter in a large Dutch oven over medium-low heat. Add the 4 large yellow onions sliced into ¼-inch rounds and cook for 30-40 minutes, stirring occasionally. You're aiming for deep golden brown caramelization—not burnt, but rich and sweet-smelling.
Here's the thing—patience is key. The onions should release their moisture and reduce down significantly. When they're properly caramelized, they'll look like amber candy and smell like a cozy autumn kitchen. If they start to stick, add a splash of beef broth to deglaze and keep them moving.
🍳 Step 2: Build the Rich Onion Broth
Once your onions are beautifully caramelized, pour in the 4 cups beef broth and bring to a gentle simmer. Stir in the 1 tbsp chopped fresh thyme, 0.5 tsp cracked black peppercorns, and 1 tsp salt. Let this mixture simmer uncovered for 15-20 minutes until the flavors meld together beautifully.
This is where the magic happens—the broth absorbs all those caramelized onion flavors. You'll smell that deep, savory aroma that makes this soup so irresistible. Taste and adjust seasoning if needed, adding more salt or pepper to your preference. The broth should be rich but not overly salty.
🥘 Step 3: Prepare the Cheesy Topping
While your soup simmers, it's time to prepare the showstopping cheese topping. In a small bowl, combine the 1.5 cups freshly grated Gruyère cheese and 1 cup freshly grated Emmental cheese. The fresher the cheese, the better it will melt into a smooth, gooey blanket over your soup.
Here's a pro tip: Use a microplane or fine grater for the cheese—this ensures it melts smoothly rather than creating clumpy bits. You can also add the 2 cloves minced garlic (if using) to the cheese mixture for an extra flavor boost. Set this aside while you prepare the crispy celery crowns.
🔥 Step 4: Create the Crispy Celery Crowns
Preheat your oven to 400°F. Cut the 6 whole celery stalks diagonally into ½-inch thick slices. In a shallow bowl, mix the 2 tbsp all-purpose flour with a pinch of salt. Toss the celery slices in this flour mixture until lightly coated.
Heat the 2 tbsp olive oil in a large oven-safe skillet over medium-high heat until shimmering. Add the floured celery in a single layer and cook for 2-3 minutes per side until golden brown and crispy. Transfer to a paper towel-lined plate to drain excess oil, then sprinkle with a pinch of salt.
🍽️ Step 5: Assemble and Serve with Crispy Bread
Return your Dutch oven of onion soup to a gentle simmer. While it heats, slice the 1 loaf French bread into ½-inch thick pieces. Brush both sides of each slice with olive oil and toast in a 400°F oven for 5-7 minutes until golden and crispy.
To serve, ladle the hot onion soup into bowls. Top each serving with a generous layer of the cheese mixture, then place a crispy celery crown on top. Serve immediately with the toasted bread on the side—this is where the real fun begins as everyone dips their bread into the gooey, cheesy goodness.
Pro Tips For Making Applebee'S Onion Soup
- COOK ON LOW HEAT: I learned this the hard way—when you caramelize the onions for Applebee’s-style soup, push the heat to medium-high until they’re deep golden, then drop it to low. Too high, and they’ll burn before they soften; too low, and you’ll wait forever. Stir often, and don’t rush it—this is where the flavor builds.
- SLICE ONIONS EVENLY: Thin, consistent slices caramelize faster and more evenly. Use a mandoline if you’re impatient (yes, even if you’re bad at it), or carefully hand-slice them about ⅛-inch thick. Thick chunks? They’ll turn mushy before they brown—no one wants that.
- SKIP THE BROTH BOIL: After adding beef broth, resist the urge to bring it to a full boil. Simmer gently instead—boiling can make the onions turn bitter and scatter everywhere. A steady, quiet bubble keeps everything tender and cohesive.
- MELT CHEESE UNDER FOIL: Sounds weird, but it works: Once the soup’s hot, cover the ramekins with foil and bake until the cheese is fully melted and bubbly. This prevents the top from browning too quickly while still getting that gooey, golden finish. No more dry, sad cheese crusts.
Creative variations of applebee's onion soup
Cheesy Variations
Swap the Gruyère and Emmental for sharp cheddar and mozzarella—mix 2 cups cheddar with 1 cup mozzarella for a bolder, creamier topping. For a vegetarian twist, use nutritional yeast (¼ cup) blended with 1 cup vegan mozzarella and 1 cup sharp cheddar.
The key is melting temperature: Gruyère melts smoothly at 400°F, while cheddar needs 425°F for that perfect stretch. 🧀
Broth Alternatives
Skip beef broth and use mushroom broth (4 cups) for a vegetarian version—add 1 tbsp soy sauce for umami depth. For a spicy kick, stir in 1 tsp smoked paprika and ½ tsp cayenne to the broth while simmering.
If you love white wine, deglaze the caramelized onions with ½ cup dry white wine before adding broth. Always reduce wine-based broths by ⅓ to concentrate flavors. 🍷
Crispy Toppings
Replace celery crowns with crispy garlic bread croutons—toss 1 cup cubed French bread with 1 tbsp olive oil, 1 minced garlic clove, and ½ tsp dried parsley. Bake at 375°F for 10 minutes until golden.
For extra crunch, top with toasted breadcrumbs (mix ¼ cup panko with 1 tbsp melted butter, toast in a dry pan for 3 minutes). 🍞
Herb Infusions
Boost flavor with fresh herbs: Add 1 tbsp chopped rosemary or 1 tsp dried tarragon to the broth for an earthy twist. For a bright finish, stir in 1 tbsp lemon zest and 1 tbsp fresh parsley before serving.
If you love citrus, squeeze 1 lemon wedge over the soup at the table—it cuts through the richness beautifully. 🌿
Regional Twists
For a Southern U.S. version, add ½ cup diced ham to the broth and top with crumbled bacon. In France, this soup often includes a splash of brandy (flambéed off) and a pinch of nutmeg.
For a Mexican-inspired bowl, stir in 1 tsp cumin and ½ tsp chili powder, then top with avocado slices and sour cream. 🌎
Make-Ahead Magic
Prep the soup base (onions + broth) up to 3 days ahead—store in an airtight container in the fridge. For the cheese topping, grate it fresh 1 hour before baking to prevent clumping. Assemble the soup 30 minutes before serving so the cheese melts perfectly in the oven.
The celery crowns can be prepped 1 day ahead—store in the fridge and crisp in the oven just before serving. ⏳

Frequently asked questions
Can I make this onion soup without beef broth?
For a vegetarian version, use 4 cups mushroom broth and add 1 tbsp soy sauce for extra umami. If you prefer a wine-based broth, deglaze the onions with ½ cup dry white wine before adding broth—just reduce it by ⅓ to concentrate the flavors. The key is balancing the richness, so taste as you go.
What's the secret to perfectly crispy celery crowns?
Thin, even slices and a light flour coating are essential. Cut celery into ½-inch thick diagonal slices, then toss in 2 tbsp flour with a pinch of salt. Cook in hot olive oil for 2-3 minutes per side until golden brown. The secret? Don't overcrowd the pan—they need space to crisp! Transfer to a wire rack to keep them crispy until serving.
Can I prepare this soup ahead of time?
Yes! Make the soup base (onions + broth) up to 3 days ahead and store in an airtight container. For the cheese topping, grate it fresh 1 hour before baking to prevent clumping. Assemble the soup 30 minutes before serving so the cheese melts perfectly in the oven. The celery crowns can be prepped 1 day ahead—just crisp them fresh before serving.
What's the best cheese substitute if I can't find Gruyère?
For a similar melt, use 2 cups sharp cheddar mixed with 1 cup mozzarella. If you're vegetarian, try 1 cup vegan mozzarella with ¼ cup nutritional yeast for that nutty depth. Remember, Gruyère melts smoothly at 400°F, while cheddar needs 425°F for that perfect stretch.
Why did my cheese not melt properly?
Cheese needs direct heat and high enough temperature. Place bowls on a baking sheet to catch drips, then bake at 400°F (or higher for cheddar) until bubbly and golden. If your cheese is clumpy, grate it fresh and avoid pre-shredded (it has anti-caking agents). For extra insurance, sprinkle cheese in layers rather than dumping it all at once.
