Serve it with toasted bread for dipping or as a standalone meal that feels like a hug in a bowl. The best part? You can adjust the spice level or cheese blend to suit your taste. Let’s get cooking—this soup is ready in under 20 minutes and worth every bite.
Ingredients for lipton onion soup mix copycat
Simple pantry staples transform into that nostalgic, cheesy comfort in record time.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 3 large | Thinly sliced, caramelized |
| Butter 🧈 | 4 tbsp | Unsalted, for caramelizing onions |
| Beef Broth 🍲 | 4 cups | Low-sodium preferred, homemade or store-bought |
| Cheddar Cheese 🧀 | 1 ½ cups | Shredded, sharp or medium |
| American Cheese 🧀 | 1 cup | Shredded, for classic Lipton taste |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| Cornstarch 🌾 | 1 tbsp | For thickening the broth |
| Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |

The onions are the soul of this soup. Yellow onions work best—they caramelize beautifully without getting bitter. Trader Joe's or Whole Foods have the freshest, but your grocery store’s regular onions will do too. Look for firm, dry ones with no bruises. The key is patience—slow cooking them until golden brown unlocks that deep, sweet flavor. I usually start them in butter, then finish with a splash of beef broth to keep them moist. Don’t rush this step, or the whole soup suffers.
No sharp cheddar? Monterey Jack or pepper jack will work, but you’ll lose that classic tang. American cheese is non-negotiable here—it’s what gives the Lipton version its signature creamy texture. Kraft singles are fine, but freshly shredded melts better. Short on milk? Heavy cream or half-and-half makes it even richer, but whole milk keeps it classic. The cornstarch is your secret weapon—it thickens the broth without making it gluey. If you’re watching carbs, you can reduce it to ½ tbsp, but the soup might be slightly thinner. The garlic powder? Fresh minced garlic is better, but the powder is a convenient shortcut.
This soup reheats beautifully—honestly tastes better the next day once everything melds. Keeps for 4-5 days in the fridge, freezes for 3 months. I always make a double batch because it disappears fast. For serving, toast the bread until crispy—dip those slices in the leftover soup for the ultimate comfort. Store leftovers with a splash of milk to keep the cheese from separating. And if you’re feeling fancy, drizzle a little olive oil on top before serving—it adds a nice finishing touch.

Step-by-step instructions for Lipton onion soup mix copycat recipe
Here's how to recreate that iconic creamy, melty cheese experience at home.
Caramelize the Yellow Onions
Melt all 4 tablespoons of butter in a large pot over medium heat. Add the 3 large yellow onions that have been thinly sliced and cook for 10 minutes, stirring occasionally. You'll see them soften and release moisture.
Reduce the heat to low and continue cooking for 20-25 minutes, stirring frequently. The onions should turn deep golden brown and develop a sweet, caramelized aroma. This slow cooking process is what gives the soup its rich, developed flavor. If the onions start to stick, add a splash of beef broth to loosen them.
Build the Creamy Broth Base
Increase the heat to medium and add all 4 cups of beef broth. Stir well to combine with the caramelized onions. Sprinkle the 1 tablespoon of cornstarch over the mixture and stir vigorously for 1 minute to dissolve any lumps.
Bring the mixture to a gentle boil, then reduce heat to low and let it simmer for 5 minutes. This allows the cornstarch to fully thicken the broth to a creamy consistency. Taste and adjust seasoning with the 0.5 teaspoon of salt and 0.25 teaspoon of black pepper. Add the 0.5 teaspoon of garlic powder and stir to combine.
Create the Melty Cheese Topping
In a separate bowl, combine the 1.5 cups of shredded cheddar cheese and 1 cup of shredded American cheese. Add the 0.5 cup of milk and stir until fully incorporated. The mixture should be smooth and ready for melting.
Keep the soup mixture warm on low heat while you prepare the bread. Toast all 8 slices of French bread until they're golden brown and crispy. The perfect toast adds that essential crunch to the classic presentation.
Assemble and Serve
Ladle about 1 cup of the warm soup into each of 4 bowls. Spoon the cheese mixture over each serving and watch as it melts into a perfect gooey blanket. The combination of sharp cheddar and classic American cheese creates that signature Lipton flavor.
Place 2 slices of toasted French bread on top of each bowl and drizzle with the 1 tablespoon of olive oil if desired. Serve immediately while the cheese is still melty and bubbly. The contrast of warm, creamy soup with crispy bread is what makes this copycat version so satisfying.
Pro Tips For Making Lipton Onion Soup Mix Copycat
- CARAMELIZE THOSE ONIONS: Don’t rush the onions—cook them on medium-low heat for 20-25 minutes until deep golden brown. I learned this the hard way: skipping this step leaves your soup tasting flat and underdeveloped. The longer they cook, the richer the flavor, even if it means staring at them like a hawk.
- GRATE THE CHEESE FINE: Skip the shredder and grate the cheddar and American cheese by hand—it melts faster and smoother. Pre-shredded cheese has anti-caking agents that make it clump and stay separate. If you’re lazy, at least pulse it in a food processor for a second or two.
- SALT THE BROTH EARLY: Season the beef broth before adding it to the onions—this balances the flavors better than trying to fix it at the end. I used to wait until the last minute, and the soup always tasted like it needed more seasoning. Trust me, your taste buds will notice.
- MELT THE CHEESE LOW AND SLOW: Once the cheese goes on, turn the heat to low and stir constantly—even if it feels like it’s taking forever. High heat burns the cheese before it melts, leaving you with a grainy, bitter mess. Patience here guarantees a creamy, velvety topping.

Frequently asked questions
Why does the original Lipton Onion Soup Mix taste different from my homemade version?
The boxed mix contains precise spice blends and preservatives that create its signature flavor. This copycat recipe uses American cheese (essential for that classic taste) and caramelized onions for depth, but the texture may vary slightly. For closer results, add ½ tsp monosodium glutamate (MSG) to the broth for umami richness. The key is patience with the onions—25 minutes of slow cooking makes all the difference!
Can I make this soup without cornstarch? What’s the best substitute?
Yes! For a gluten-free option, use 1 tbsp arrowroot powder or 1 tbsp all-purpose flour instead. If avoiding thickeners entirely, simmer the broth longer (15-20 minutes) to reduce naturally. The soup will be thinner but still delicious. For extra creaminess, stir in ½ cup sour cream at the end.
How do I prevent the cheese from separating when reheating leftovers?
Always reheat with a splash of milk or broth—2-3 tablespoons per bowl—to keep the cheese smooth. Stir constantly over low heat until just melted. For storage, let the soup cool slightly before refrigerating, and press plastic wrap directly on the surface to minimize a skin. Freeze portions in airtight containers with parchment paper between layers.
Is this recipe kid-friendly? How can I make it milder for picky eaters?
For sensitive palates, reduce the garlic powder to ¼ tsp and omit the black pepper. Use mild cheddar instead of sharp varieties, and blend the soup briefly for a smoother texture. Serve with buttered noodles or soft breadsticks to make it more approachable. The sweet caramelized onions are usually a hit with kids!
Can I double this recipe for a crowd? What’s the best pot size?
Yes, but use a 6-8 quart pot for even cooking. Double all ingredients except the cheese—add it just before serving to prevent clumping. For large gatherings, pre-make the caramelized onions and broth base, then reheat separately. Keep the cheese mixture in a separate pot on low heat until serving. This keeps everything fresh and melty!
