Ingredients for lipton onion soup red potato
Restaurant-quality onion soup with tender red potatoes and a golden crispy top—all in one pot.
| Ingredient | Amount | Notes |
|---|---|---|
| Lipton Onion Soup Mix 🧅 | 2 tbsp | Granulated, not powdered |
| Red Potatoes 🥔 | 1 ½ lb | Medium size, unpeeled |
| Yellow Onion 🧅 | 1 whole | Medium, sliced thin |
| Butter 🧈 | 4 tbsp | Unsalted, cold cubed |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Chicken Broth 💧 | 2 cups | Low-sodium preferred |
| Whole Milk 🥛 | ½ cup | Warmed slightly |
| Garlic Cloves 🧄 | 2 cloves | Minced for depth |
| Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh |
| Bread Crumbs 🍞 | ½ cup | Panko for crispiness |
| Sharp Cheddar Cheese 🧀 | ½ cup | Shredded, for topping |
| Olive Oil 🫒 | 1 tbsp | For crispy top |
The Lipton Onion Soup Mix is the foundation, but don't use the powdered kind from the can—granulated works best for proper dissolution. For potatoes, red or Yukon Gold hold their shape beautifully. If you can't find them, russets work too, but they'll break apart more. The butter should be cold when added to create that perfect crispy crust later. I always grab Kirkland brand butter from Costco for this recipe—it's reliable and affordable. For the heavy cream, full-fat is non-negotiable here; it delivers that velvety texture the recipe promises.
No Lipton granules? Dried onion powder plus a pinch of sugar mimics the flavor, though it won't have the same depth. Swapping heavy cream for half-and-half cuts richness but keeps it creamy. The chicken broth can be subbed with vegetable broth for a vegetarian version, though the flavor profile shifts slightly. For the crispy topping, panko breadcrumbs are ideal, but regular breadcrumbs toasted in the oven work in a pinch. The sharp cheddar adds a nice tang—Parmigiano-Reggiano works too if you prefer a more complex flavor. Prefer your potatoes roasted? Toss them in olive oil and roast at 400°F for 20 minutes before adding to the pot.
This soup reheats beautifully—simmer gently to restore creaminess. Store leftovers in the fridge for up to 4 days or freeze for 3 months. The crispy topping loses its crunch when reheated, so I always make a fresh batch for serving. For meal prep, cook the soup without the topping, then assemble and crisp fresh when ready to serve. The red potatoes stay tender for days, making this a great make-ahead option for busy weeknights. Keep the Lipton mix in an airtight container to preserve its flavor—it's the secret weapon here.

Step-by-step instructions for Lipton onion soup red potato casserole
Follow this method to create a rich, creamy potato dish with a golden, crispy breadcrumb topping.
Parboil and Slice the Potatoes
Place the 1.5 lb red potatoes in a large pot and cover with cold water by 2 inches. Add the 2 tbsp Lipton Onion Soup Mix and bring to a boil over high heat. Once boiling, reduce heat to medium and simmer for 8-10 minutes until the potatoes are slightly tender but still firm to the bite.
Drain the potatoes and let them cool slightly before peeling. Using a sharp knife, slice them into ¼-inch thick rounds. The potatoes should hold their shape but still be tender enough to cook through in the oven. Keep them in a bowl while you prepare the other components.
Build the Creamy Onion Base
In a large oven-safe skillet, melt 2 tbsp of the 4 tbsp butter over medium heat. Add the sliced 1 whole yellow onion and cook for 5-6 minutes until softened and translucent. Stir in the 2 minced garlic cloves and cook for 30 seconds until fragrant.
Sprinkle the 0.5 tsp dried thyme over the onions and stir to combine. Pour in the 2 cups chicken broth and bring to a gentle simmer. Let it reduce by half, about 5 minutes, until the liquid is thickened and coats the back of a spoon.
Layer the Potatoes and Create the Creamy Sauce
Arrange half of the sliced potatoes in an even layer over the onion mixture in the skillet. Season lightly with the 0.5 tsp salt and 0.25 tsp black pepper. In a small bowl, whisk together the 1 cup heavy cream, 0.5 cup whole milk, and remaining 2 tbsp butter until smooth. Pour this mixture evenly over the potatoes.
Top with the remaining potato slices, pressing down gently to ensure even contact with the sauce. Cover the skillet with a lid or foil and transfer to a preheated 375°F oven. Bake for 30 minutes until the potatoes are tender and the sauce has thickened.
Prepare the Crispy Topping and Finish Baking
In a small bowl, combine the 0.5 cup bread crumbs, 0.5 cup shredded sharp cheddar cheese, and 1 tbsp olive oil. Mix until the crumbs are evenly coated. After the initial 30 minutes of baking, remove the skillet from the oven and sprinkle the breadcrumb mixture evenly over the top of the potatoes.
Return to the oven and bake for an additional 15-20 minutes until the topping is golden brown and crispy. The internal temperature of the potatoes should reach 200°F, ensuring they're fully cooked through. Let the casserole rest for 5 minutes before serving to allow the sauce to set slightly.
Serve Warm with Fresh Garnishes
Using a spatula, carefully transfer the casserole to a serving dish. Garnish with additional black pepper and fresh parsley if desired. The creamy onion sauce should coat each layer of potato, while the crispy breadcrumb topping adds satisfying texture with every bite.
This one-pot dish delivers all the promised elements: a rich, creamy onion-potato filling and a perfectly crispy breadcrumb topping. Serve immediately while hot and enjoy the comforting flavors of this classic comfort food.
Pro Tips For Making Lipton Onion Soup Red Potato
- CHOP POTATOES EVENLY: I learned this the hard way—uneven chunks mean some potatoes turn to mush while others stay rock-hard. Cut them into 1-inch pieces before peeling if you’re impatient (just scrub them well), or peel first and slice consistently. No one wants a soup with a "potato lottery."
- SAUTÉ ONIONS LOW AND SLOW: The soup mix tastes flat when you rush the onions. Cook them in butter over medium-low heat for 8-10 minutes until deep golden, not browned. This builds flavor—skip it, and you’re just eating powdered onion dust with potatoes.
- WHISK IN CREAM GRADUALLY: Dumping cold heavy cream into hot soup will curdle it faster than you can say "soup’s ruined." Temper it first by whisking in ¼ cup at a time while stirring constantly. Your future self will thank you when the sauce stays silky.
- USE 2 TABLESPOONS OF MIX PER CUP OF WATER: The box says "1 tablespoon," but that’s anemic. Double it for a richer, more concentrated flavor—especially if you’re adding extra potatoes. Trust me, the soup won’t taste like "onion soup mix" anymore.
Health benefits of this recipe
Comfort Food Energy
This dish is a perfect energy-boosting meal thanks to its balanced combination of complex carbs from the red potatoes and protein from the heavy cream and chicken broth.
The red potatoes provide slow-digesting carbohydrates that fuel your body with steady energy throughout the day, making this an ideal choice for busy weeknights or post-workout recovery. The Lipton Onion Soup Mix adds a savory depth that enhances flavor without adding empty calories. 💪
Vitamin and Mineral Boost
The red potatoes in this recipe are packed with vitamin C, potassium, and fiber, which support immune function and digestion. A single serving delivers about 20% of your daily vitamin C needs, helping your body absorb iron from other foods you eat.
The onions contribute flavonoids and antioxidants, while the heavy cream provides calcium and vitamin A for bone health and vision. It’s a one-dish powerhouse of essential nutrients.
Protein for Satiety
While this recipe isn’t a high-protein dish, the heavy cream and chicken broth contribute about 10 grams of protein per serving, which helps keep you full and satisfied.
The cheddar cheese in the crispy topping adds an extra 5 grams of protein, making it a more balanced meal than traditional onion soup. This protein content helps stabilize blood sugar levels, preventing energy crashes later in the day.
Low-Fat Option
If you're watching your fat intake, you can easily reduce the richness by swapping half-and-half for the heavy cream or using low-fat cheddar cheese in the topping. The olive oil in the crispy topping can also be reduced by ½ tablespoon without sacrificing flavor.
This adjustment cuts calories while keeping the dish creamy and satisfying—proof that comfort food can align with dietary goals. 💡
Digestive Benefits
The fiber-rich red potatoes and onions in this recipe promote healthy digestion and gut health. The soluble fiber in potatoes helps regulate blood sugar levels, while the prebiotic properties of onions support a healthy gut microbiome.
This makes the dish not just comforting but also gentle on your digestive system, especially after a long day. The thyme in the recipe adds anti-inflammatory benefits, rounding out the health perks.
Meal Prep Friendly
One of the biggest health advantages of this recipe is its make-ahead convenience. You can prepare the entire dish (minus the crispy topping) up to 4 days in advance and store it in the fridge.
When reheating, simply add the breadcrumb topping fresh before baking for 15-20 minutes to restore that satisfying crunch. This eliminates the need for last-minute cooking, making it a stress-free option for health-conscious home cooks. ✨

Frequently asked questions
Can I use regular potatoes instead of red potatoes?
Yes, but the texture will differ. Red potatoes hold their shape beautifully, making them ideal for this recipe. If you must use russets or Yukon Golds, they'll break apart more easily and absorb more liquid. For a similar effect, parboil them slightly longer (12-15 minutes) to firm them up before slicing.
How do I make this dish vegetarian?
Swap the chicken broth for vegetable broth and replace the heavy cream with coconut cream or cashew cream for richness. The flavor will be slightly different but still delicious. You can also add nutritional yeast to the crispy topping for a cheesy flavor without dairy.
Why does my crispy topping keep getting soggy?
Soggy toppings usually happen when moisture escapes during baking. To fix this, pat the breadcrumbs completely dry before mixing with olive oil and cheese. Also, ensure your potatoes are fully cooked before adding the topping. Bake the topping uncovered for the last 5 minutes to help it crisp up.
Can I make this in a slow cooker?
Parboil and slice the potatoes as directed, then combine everything except the crispy topping in your slow cooker. Cook on low for 4-5 hours or high for 2-3 hours until potatoes are tender. For the crispy top, transfer to an oven-safe dish and broil for 3-5 minutes after adding the breadcrumb mixture.
What's the best way to reheat leftovers?
Reheat in the oven at 350°F for 15-20 minutes to restore creaminess. For the crispy topping, add fresh breadcrumbs and broil for 3-5 minutes at the end. Microwaving works in a pinch, but the texture will be less satisfying. Always reheat covered until steaming hot.
