Soups & Stews
This Lipton Onion Soup Mix copycat recipe delivers the same rich, savory depth as the classic canned version—but with homemade ingredients and a perfectly melty cheese topping.
The secret lies in caramelizing onions until they're deep golden, then balancing them with just the right amount of beef broth, garlic, and spices. I've tested this recipe dozens of times to ensure it captures that signature umami flavor without relying on processed shortcuts.
The beauty of making this from scratch is controlling the texture and flavor at every step. You'll start with a deep, aromatic base from slow-cooked onions, then build layers of savory depth with beef broth and a precise blend of spices.
The result is a soup that's rich, hearty, and packed with that familiar onion soup taste—just like the one you remember from childhood.
What sets this apart is the creamy, melty cheese topping that's even better than the canned version. We'll use sharp cheddar and a touch of cream cheese for that perfect blend of tangy and velvety.
The cheese melts directly into the hot soup, creating pockets of gooey goodness in every bite—no pre-shredded cheese or canned convenience here.
This recipe is perfect for chilly evenings when you crave comfort food that warms you from the inside out. It comes together in about 45 minutes, with most of that time spent simmering for maximum flavor development.
Serve with crusty bread to soak up every last drop of that rich, cheesy broth. Let's get cooking!
Ingredients for lipton onion soup mix copycat
Simple pantry staples transform into that nostalgic Lipton flavor—rich, cheesy, and comforting.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 3 large | Thinly sliced for caramelizing |
| Butter 🧈 | 4 tbsp | Unsalted, for caramelizing onions |
| Beef Broth 💧 | 4 cups | Low-sodium preferred, homemade or high-quality |
| Garlic Cloves 🧄 | 4 cloves | Minced, for aromatic depth |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening soup base |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme leaves |
| Dried Parsley Flakes 🌿 | 1 tsp | For fresh herb finish |
| Salt 🧂 | 1 tsp | Adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Sharp Cheddar Cheese 🧀 | 2 cups | Freshly grated, block preferred |

The onions are everything here. Yellow onions caramelize best—skip red or white, they burn too fast. Grab the biggest, firmest ones from the grocery store's produce section, not the pre-sliced sad bags. Costco or Trader Joe's usually have the best quality. Thinly slice them yourself—thick pieces won't caramelize properly. If you're short on time, pre-sliced onions work, but they won't have that same depth of flavor. The butter should be unsalted so you control the seasoning later. Trust me, this step is worth the 20 minutes of patience—it's what makes this taste homemade.
No beef broth? Chicken broth with a bouillon cube works in a pinch, but you'll lose that meaty depth. Fresh thyme is ideal, but dried works fine at the same amount. If you've got Italian seasoning, use half a teaspoon instead. The sharp cheddar needs to be real block cheese—pre-shredded gets gummy when melted. For the cream cheese, full-fat is non-negotiable—low-fat versions won't get that perfect velvety texture. The bread should be crusty—French or sourdough works best, but whatever you've got will do. Toast it while the soup simmers for maximum crunch.
This soup tastes even better the next day—honestly, it improves with time. Store leftovers in the fridge for up to 4 days, but the cheese topping will separate slightly. Just stir it back together when reheating. For freezing, portion before adding cheese—it reheats best when added fresh. The caramelized onions can be prepped ahead and stored in the fridge for 3 days. I always make a double batch because it disappears fast, especially with that gooey cheese on top.

Step-by-step instructions for creamy onion soup with melty cheese top
Here's how to build that iconic Lipton-style flavor from scratch—rich, creamy, and topped with perfect melty cheese.
Caramelize the Onions Slowly
Melt the 4 tbsp butter in a large Dutch oven over medium-low heat. Add the 3 large yellow onions, sliced thinly, and stir to coat them in the butter. Let them cook undisturbed for 10 minutes—this gives them time to release moisture and start caramelizing.
After that initial period, stir occasionally and cook for another 20-25 minutes until the onions turn deep golden brown and sweet-smelling. If they start to stick, add a splash of beef broth to deglaze. Patience here is key—the deeper the caramelization, the richer the flavor. You're aiming for a jam-like consistency at the bottom of the pot.
Build the Flavor Base
Once the onions are beautifully caramelized, stir in the 4 cloves minced garlic and cook for 30 seconds until fragrant. Add the 2 tbsp all-purpose flour and stir constantly for 1-2 minutes to cook off the raw flour taste.
Slowly pour in the 4 cups beef broth while whisking to prevent lumps. Bring the mixture to a gentle simmer and let it cook for 15 minutes until slightly thickened. Add the 1 tsp dried thyme, 1 tsp dried parsley flakes, 1 tsp salt, and 0.5 tsp black pepper, stirring to combine. This step develops the deep, savory foundation that makes homemade soup so much better than canned.
Create the Creamy Texture
Reduce heat to low and stir in the 4 oz cream cheese until completely melted and smooth. The soup should become luxuriously thick and creamy. If it's too thick, whisk in 2-3 tablespoons of warm broth to reach your preferred consistency. Taste and adjust seasoning—this is where you can really fine-tune the flavor to your liking.
Keep the soup warm over low heat while you prepare the cheese topping. The residual heat will help maintain the creamy texture without curdling the cheese mixture.
Prepare the Melty Cheese Topping
In a small bowl, combine the 2 cups sharp cheddar cheese with the 1 tbsp extra-virgin olive oil. Mix until the cheese is evenly coated with oil, which helps it melt more smoothly. Spread this mixture evenly over the soup in the Dutch oven.
Place the Dutch oven under a broiler for 2-3 minutes until the cheese is bubbly and golden brown on top. Watch it closely—you want it to melt completely but not burn. The broiler creates that perfect crispy, melty top that's the signature of great onion soup.
Serve with Crusty Bread
Ladle the creamy soup into bowls, making sure to get a generous portion of that melted cheese on top. Serve immediately with slices of crusty bread for dipping. The contrast between the warm, creamy soup and the crisp bread is what makes this dish so satisfying.
Pro tip: If you're serving this to a crowd, keep the cheese mixture in a small bowl in the oven on low heat while you serve. Just spoon it over each portion right before serving to maintain that perfect melty consistency.
Pro Tips For Making Lipton Onion Soup Mix Copycat
- Sweat, Don’t Burn: Onions should be soft and translucent, not browned or crispy—this isn’t caramelizing. Use medium-low heat and stir every 30 seconds, or they’ll turn bitter before the flour even hits. I learned this the hard way after making my first batch taste like a sad, overcooked onion ring.
- Use Cold Butter: Add the butter to the onions after they’ve been sweating for 5 minutes. Cold butter melts slower and coats the onions evenly, preventing hot spots that can burn the garlic later. Skip the pre-melted butter—it’s a shortcut that ruins texture.
- Whisk the Roux Fast: Once you toss in the flour, crank the heat to medium-high and whisk like you’re trying to win a race. Let it cook for 1-2 minutes until it’s a light golden paste—this builds flavor and thickens the soup properly. I used to walk away for "just a second," and the roux would turn gray and taste like regret.
- Salt the Broth Early: Add half the salt (or more, if using low-sodium broth) with the broth, not at the end. The roux soaks up flavor like a sponge, and salting late means you’ll either miss it or overdo it. Trust me, your taste buds will notice the difference.
Dietary considerations for lipton onion soup mix copycat
Gluten-Free Adaptation
Replace the 2 tbsp all-purpose flour with 2 tbsp gluten-free flour blend (like Bob's Red Mill 1:1) to keep the soup thick and creamy. I've tested this with King Arthur gluten-free flour—it works beautifully without altering the texture.
Just whisk it vigorously to prevent clumping when adding to the broth. 🌾
Dairy-Free Option
Swap the sharp cheddar and cream cheese for 2 cups dairy-free cheddar shreds (like Violife or Daiya) and 4 oz dairy-free cream cheese (like Kite Hill).
The flavor won't be identical, but it's still rich and satisfying. For extra creaminess, stir in ¼ cup coconut milk after removing the pot from heat.
Low-Sodium Version
Use low-sodium beef broth (like Swanson or Pacific Foods) and reduce added salt to ½ tsp. Boost umami with 1 tsp Worcestershire sauce (check for gluten-free if needed) or ½ tsp MSG for depth.
Taste as you go—you might need just a pinch more salt at the end. The caramelized onions provide natural sweetness that balances the flavor beautifully.
Vegetarian Swap
Replace the beef broth with 4 cups vegetable broth (like Imagine or Pacific) and add 1 tbsp soy sauce or 1 tsp miso paste for umami. Use mushroom powder (like 1 tsp nutritional yeast) to enhance the savory depth.
The caramelized onions still shine as the star ingredient, making this version surprisingly hearty. 🌱
Keto-Friendly Adjustments
Skip the flour entirely and thicken the soup by simmering the onions and broth longer—about 30 minutes instead of 15. Add 1 tbsp xanthan gum or 1 tsp psyllium husk powder if extra thickness is needed.
Use full-fat dairy and serve with low-carb bread (like Caulipower or Mission Carb Balance) for dipping.
Allergy-Friendly Tips
For nut allergies, avoid any nut-based thickeners and stick with xanthan gum or arrowroot powder. If you're sensitive to sulfites, use fresh herbs instead of dried (like 1 tbsp fresh thyme instead of 1 tsp dried).
Always check labels on broths and cheeses for hidden allergens—brands like Annie's and Organic Valley have good allergy-friendly options.

Frequently asked questions
Can I make this onion soup without caramelizing the onions?
The caramelization is key for that deep, sweet flavor that makes this taste like the canned version. If you're short on time, sauté the onions until soft (8-10 minutes) instead, but expect less richness. For maximum flavor, don't skip this step—it's what makes homemade soup taste so much better.
Why does my cheese topping get grainy when melted?
Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Always use block cheese and grate it yourself. For extra creaminess, mix the cheese with a little olive oil before adding it to the soup. If it still separates, stir vigorously while reheating to redistribute the fat.
Can I use powdered onion soup mix instead of making it from scratch?
Use 2 tbsp powdered onion soup mix (like Lipton's) instead of the flour and spices. Stir it into the caramelized onions with the broth. This cuts prep time significantly while keeping the authentic flavor. Just adjust salt to taste since some mixes are saltier than others.
How do I make this soup spicier?
Add ½ tsp smoked paprika or ¼ tsp cayenne pepper to the flour mixture. For heat without dryness, stir in 1 tbsp hot sauce (like Frank's RedHot) at the end. If you love kick, try adding a pinch of red pepper flakes directly to the melted cheese topping before broiling.
Can I prepare this soup ahead of time?
Yes! Make the soup base (without cheese) up to 3 days ahead and store it refrigerated. Reheat gently, then add fresh cheese topping when serving. For freezing, portion the soup before adding cheese—it reheats best when added fresh. The caramelized onions can be prepped separately and stored for 3 days in the fridge.
