Ingredients You’ll Need
The magic of the Simple Spicy Jalapeño and Cheddar Cheese Sauce Recipe lies in its straightforward, but well-chosen ingredients. Each one plays a starring role, from providing the spicy undertone to the luscious texture, and even adding depth and brightness to the final sauce.

- 2 tablespoons white wine: Adds a subtle complexity and depth of flavor.
- 2 cups heavy cream: Creates the smooth, luscious base perfect for melting cheese into.

How to Make Simple Spicy Jalapeño and Cheddar Cheese Sauce Recipe
Step 1: Prepare the Fresh Ingredients
Start by slicing the jalapeños and onions carefully. For this recipe, 6 slices of jalapeño roughly equal half a small pepper, but feel free to add more slices if you crave even more heat. The onions, about three-quarters of a cup sliced, bring a sweet and savory base that makes this sauce sing.
Step 2: Sauté the Jalapeños, Onions, and Peppercorns
Heat a medium frying pan over medium-high heat and add the oil once the pan shimmers. Toss in the sliced jalapeños, onions, and honest-to-goodness whole peppercorns. This step sautés the veggies until they soften and release their fantastic flavors.
Step 3: Season and Cook the Veggies
Sprinkle in kosher salt to help draw out moisture and enhance flavor. Cook for 3 to 5 minutes, stirring occasionally until everything becomes tender and fragrant — this is the aromatic foundation of your sauce.
Step 4: Deglaze with White Wine and Vinegar
Add the white wine vinegar and white wine to the pan. These liquids add bright, acidic notes that balance the richness of the cheese and cream, while also picking up any caramelized bits stuck to the pan for extra tastiness.
Step 5: Simmer Until Liquid Absorbs
Continue cooking until the liquid mostly evaporates and the flavors have concentrated into the jalapeños and onions, creating a rich, flavorful base.
Step 6: Stir in Heavy Cream and Warm Through
Pour in the heavy cream and stir gently. Once the cream is warm (but not boiling), remove the pan from heat and let all those wonderful flavors steep together for about 30 minutes — patience here really pays off.
Step 7: Prepare the Cheeses
While the cream steeps, chop the American cheese into cubes and shred the sharp cheddar. This makes it easier for the cheeses to melt evenly in the next steps.
Step 8: Strain Out the Solids
After steeping, pour the cream mixture through a fine sieve to strain out the jalapeños, onions, and peppercorns, leaving a smooth, infused cream that carries all those vibrant flavors.
Step 9: Melt the Cheese in the Cream
Return the smooth cream to the pan and heat over medium, stirring occasionally. As it begins to bubble lightly at the edges, reduce heat to low and gradually whisk in the American and cheddar cheeses by small batches. Keep whisking until the sauce becomes perfectly smooth and velvety.
Step 10: Serve Hot and Enjoy
This Simple Spicy Jalapeño and Cheddar Cheese Sauce Recipe is best enjoyed freshly made, while it still delivers that creamy, spicy, cheesy goodness. If the sauce thickens too much, gently thin it with a splash of milk to your preferred consistency.

Make Ahead and Storage
Storing Leftovers

Freezing
You can freeze this sauce for up to 2 months. To preserve the smooth texture, thaw it slowly overnight in the fridge and stir well before reheating to recombine any separation that may occur.

Reheat gently over low heat on the stove, whisking frequently. If needed, add milk a tablespoon at a time to achieve the perfect pourable texture. You can also microwave the sauce in short bursts, stirring in between to keep it smooth.

Ingredients
Vegetables and Spices

Cheese
- 2 cups American cheese (8 ounces, cubed)
- 2 cups sharp cheddar cheese (8 ounces, shredded)
Instructions
- Prepare the jalapeños and onions: Slice the jalapeños into 6 slices including seeds for heat. Slice onions to measure 3/4 cup, about one very small or half a medium onion.
- Heat oil and sauté aromatics: Set a medium frying pan over medium-high heat. When hot, add 1 tablespoon of oil that shimmers immediately. Add sliced jalapeños, sliced onion, and 2 tablespoons whole peppercorns to the pan.
- Season and sauté: Sprinkle 1 1/2 teaspoons kosher salt over the mixture and sauté for 3-5 minutes until softened and fragrant.
- Add vinegar and wine: Pour in 1 tablespoon white wine vinegar and 2 tablespoons white wine, continuing to sauté.
- Reduce liquid: Continue cooking until the liquid has mostly evaporated and the flavors are absorbed into the jalapeños and onions.
- Add cream and warm: Pour in 2 cups heavy cream and stir. Warm the cream for about 30 seconds without letting it bubble, then remove from heat.
- Steep flavors: Let the cream steep with the sautéed ingredients for 30 minutes to meld the flavors.
- Prepare cheeses: While steeping, chop 2 cups (8 ounces) American cheese into cubes and shred 2 cups (8 ounces) sharp cheddar cheese. Set aside.
