Ingredients for betty crocker onion soup
Fifteen ingredients, nostalgic flavors, and that perfect crispy-gooey bread topping you crave.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 3 whole | Thinly sliced, about 3 cups |
| Unsalted Butter 🧈 | 4 tbsp | For caramelizing onions |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening broth |
| Beef Broth 💧 | 4 cups | Low-sodium preferred |
| Dry White Wine 🍷 | ½ cup | Or substitute with extra broth |
| Chicken Broth 💧 | 2 cups | For additional depth |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme |
| French Bread Loaf 🍞 | 1 whole | Crust removed, sliced |
| Shredded Sharp Cheddar Cheese 🧀 | 1 ½ cups | Freshly shredded preferred |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For bread topping |
| Garlic Powder 🧄 | ½ tsp | For bread seasoning |
| Dried Parsley 🌿 | ¼ tsp | For garnish |
| Grated Parmesan Cheese 🧀 | ¼ cup | For garnish |
The onions are the star here—yellow onions work best for that classic sweetness. Grab the biggest, freshest ones you can find (the local farmers market has the best), and slice them paper-thin for even caramelization. If you’re in a rush, pre-sliced onions from the grocery store’s salad bar section will save time, though they won’t caramelize quite as beautifully. Butter matters too—unsalted gives you control over seasoning, and European-style butter like Plugrá has more flavor. For the broth, low-sodium is key so you can season to taste.
No white wine? Extra beef broth plus a splash of apple cider vinegar mimics the acidity perfectly. The flour should be all-purpose—bread flour gets too thick. For the bread topping, French bread is ideal, but sourdough or Italian bread works too. Just make sure it’s fresh—stale bread won’t crisp up right. Short on cheddar? Swiss or Gruyère adds a lovely nutty depth. The garlic powder can be skipped if you’re not a fan, but trust me, it elevates everything. For the garnish, fresh parsley if you’ve got it, dried if not—no judgment.
This soup tastes even better the next day—4-5 days in the fridge, covered. The bread topping? Make it ahead and store it separately—it reheats beautifully. For serving, I like to portion the soup into bowls, add the bread topping, and broil for 2-3 minutes until bubbly. Garnish with extra cheese and parsley right before serving. Leftovers? The bread topping freezes well for up to 3 months—just reheat in the oven to crisp up again.

Step-by-step instructions for Betty Crocker-style onion soup
Here’s how to create that iconic cheesy bread crust—crispy at first, meltingly gooey by the end.
Caramelize the Onions Until Deeply Sweet
Melt all 4 tablespoons unsalted butter in a large Dutch oven over medium-low heat. Add the 3 whole yellow onions, thinly sliced, and cook them slowly for 45-50 minutes. Stir occasionally, but let them develop that rich, golden caramelization without rushing.
You’ll know they’re ready when the onions are deep golden brown and their edges start to crisp slightly at the edges. This slow cooking transforms their natural sugars into complex sweetness—the foundation of great onion soup. If they start to stick, add a splash of the dry white wine to deglaze, scraping up those flavorful browned bits.
Build the Rich, Thickened Broth Base
Once the onions are perfectly caramelized, sprinkle in the 2 tablespoons all-purpose flour and stir vigorously for 1-2 minutes to cook out the raw flour taste. Gradually whisk in the 4 cups beef broth and 2 cups chicken broth, then add the 0.5 cup dry white wine, 1.5 teaspoons salt, 0.5 teaspoon black pepper, and 0.5 teaspoon dried thyme. Bring everything to a gentle simmer.
Let the soup cook uncovered for 20-25 minutes until it thickens slightly and the flavors meld together. You want it to coat the back of a spoon but still have a velvety texture—not gluey or overly reduced. Taste and adjust seasoning if needed; this is your chance to balance the sweetness of the onions with the savory broth.
Prepare the Cheesy Bread Topping
While the soup simmers, remove the crust from the 1 whole French bread loaf and slice it into ¼-inch thick pieces. Arrange the slices in a single layer on a baking sheet, brush lightly with the 1 tablespoon extra-virgin olive oil, and sprinkle with 0.5 teaspoon garlic powder. Bake at 375°F for 5-7 minutes until the bread is just beginning to crisp at the edges.
Remove the bread from the oven and immediately sprinkle each slice with 1 tablespoon of the 1.5 cups shredded sharp cheddar cheese (about 0.375 cups per slice). Return to the oven for 1-2 minutes just until the cheese starts to melt and bubble. The key here is speed—you want the cheese to soften but not fully melt before it goes on the soup.
Assemble and Bake to Crispy-Gooey Perfection
Ladle the warm onion soup into 4 oven-safe bowls (or a single large baking dish if serving family-style). Arrange the cheesy bread slices on top of each serving, pressing down gently so they make contact with the soup. This ensures maximum surface area for that glorious crispy-gooey transformation.
Transfer the bowls to a 400°F oven and bake for 8-10 minutes until the bread edges are deep golden brown and the cheese is fully melted and bubbling. Watch closely in the last minute—you want the bread to crisp up while the cheese underneath stays creamy. The contrast between the crispy top and gooey cheese is what makes this dish legendary.
Garnish and Serve Immediately
Remove the soup from the oven and let it sit for 1-2 minutes to set slightly. Sprinkle each serving generously with the remaining 0.375 cups shredded sharp cheddar cheese and the 0.25 cup grated parmesan cheese, then finish with a pinch of 0.25 teaspoon dried parsley. The parsley adds a fresh contrast to the rich, cheesy flavors.
Serve immediately while the bread is still crisp and the cheese is molten. The first bite should deliver that perfect combination of crunchy, cheesy bread on top and rich, caramelized onion soup underneath. If you can’t eat it all at once, cover loosely with foil to keep the bread from losing its crispness.
Pro Tips For Making Betty Crocker Onion Soup
- SWEEP THE POT FREQUENTLY: I learned this the hard way—letting the onions caramelize without stirring turns them into a sad, uneven sludge. Every 3-4 minutes, scrape up those browned bits with a wooden spoon. Yes, it’s tedious, but those fond bits are where the flavor lives.
- USE COLD BUTTER: Plopping warm butter straight into the pot? That’s how you get greasy soup. Take the butter out of the fridge 10 minutes before cooking, then cut it into small cubes. It melts slower, coats the onions better, and prevents a greasy mess.
- DEGLAZE WITH WINE FIRST: Skip the broth for the first splash—pour in that dry white wine right after the flour-butter roux forms. Let it bubble for 2 minutes to cook off the alcohol before adding broth. This keeps the soup from tasting flat or boozy.
- SALT THE BROTH LATER: The beef broth likely already has salt. Taste it first—if it’s even mildly salty, hold off on adding extra until the very end. Over-salting here ruins the balance, and you can’t fix it. Trust me, I’ve tried.
Serving suggestions for leftovers
Classic Bread Bowl
For a fun twist, serve this onion soup in hollowed-out French bread bowls instead of regular bowls. Cut the top off a baguette or sourdough loaf, scoop out the insides (save for croutons!), and bake at 375°F for 10 minutes before filling with soup and topping.
The bread absorbs the rich broth beautifully, creating a one-bite wonder that kids and adults love. 🍞
Cheese Variations
Swap the sharp cheddar for other melty cheeses to change up the flavor profile. Gruyère adds a nutty depth, while Swiss brings a mild sweetness. For a vegetarian-friendly option, use nutritional yeast (about 3 tbsp) mixed with cashew cheese for a dairy-free topping that still melts beautifully.
Always shred cheese fresh—pre-shredded varieties contain anti-caking agents that prevent proper melting. 🧀
Side Pairings
A simple arugula salad with lemon vinaigrette cuts through the richness of the soup. Toss 4 cups baby arugula with 2 tbsp olive oil, 1 tbsp lemon juice, and a pinch of salt and pepper.
For heartier sides, serve with roasted Brussels sprouts (tossed in 1 tbsp balsamic glaze) or crispy roasted potatoes (seasoned with rosemary and garlic). These pairings balance the creamy, cheesy soup perfectly. 🥗
Beverage Pairings
A crisp white wine like Sauvignon Blanc or Chardonnay complements the soup’s richness. For beer lovers, a light lager (like Peroni) or wheat beer (like Blue Moon) cleanses the palate without overpowering.
If you prefer non-alcoholic options, sparkling apple cider or iced hibiscus tea add a refreshing contrast to the warm, cheesy flavors. 🍷
Make-Ahead Tips
Prepare the soup base up to 3 days ahead and store it in an airtight container in the fridge. Reheat gently on the stovetop over medium-low heat until warmed through. For the bread topping, assemble it (without baking) up to 1 day ahead and refrigerate.
When ready to serve, bake as directed—it reheats beautifully and crisps up again. Freeze the cheesy bread topping (unbaked) for up to 3 months for quick meals. ❄️
Garnish Ideas
Elevate your soup with fresh green onions (chopped) or chives for a bright pop of color. A drizzle of hot honey (mix 1 tbsp honey with ½ tsp cayenne) adds a sweet-spicy kick.
For a herbaceous finish, sprinkle with fresh thyme leaves or basil. These garnishes add texture and freshness that contrast the rich, cheesy flavors. 🌿

Frequently asked questions
Can I make this onion soup without wine?
Skip the wine and use an extra ½ cup beef broth plus 1 teaspoon apple cider vinegar to mimic the acidity. The vinegar adds brightness that balances the sweet onions. For a completely alcohol-free version, omit both and just add an extra pinch of salt to compensate for the missing depth.
How do I keep the bread topping crispy when reheating leftovers?
Reheat leftovers in the oven instead of the microwave. Place the covered soup in a 350°F oven for 10-12 minutes—just until warmed through. The residual heat will crisp the bread edges again. For extra insurance, sprinkle a little extra cheese on top during reheating to restore that gooey texture.
What’s the secret to perfectly caramelized onions?
Patience and low heat are key! Cook the onions over medium-low heat for 45-50 minutes, stirring occasionally. They should turn deep golden brown with slightly crisp edges. If they brown too quickly, reduce the heat. A splash of wine or broth can help deglaze and prevent burning while adding flavor.
Can I use a different type of cheese for the topping?
Yes! While sharp cheddar is classic, try Gruyère for nutty depth or Swiss for mild sweetness. For a dairy-free option, mix 3 tablespoons nutritional yeast with ½ cup cashew cheese—it melts beautifully. Just shred cheese fresh (not pre-shredded) to avoid anti-caking agents that prevent proper melting.
Why does my onion soup taste too sweet?
Over-caramelized onions or too much salt can make the soup taste sweet. Balance it by adding 1 teaspoon Dijon mustard or a pinch of black pepper to cut the sweetness. The broth should be savory, so taste and adjust seasoning before serving. A splash of vinegar or lemon juice can also help rebalance flavors.
