This article covers five distinct sauces that turn a simple pork tenderloin sandwich into a memorable meal. From a classic creamy horseradish sauce to a tangy mustard-based option and a sweet bourbon glaze, each recipe is quick to make and uses ingredients you likely have on hand. The key is balancing the lean, mild flavor of pork with sauces that are bold, tangy, or slightly sweet—these recipes do exactly that.
Ingredients
For the Classic Creamy Horseradish Sauce (makes about 1 cup / 240 ml):
- 1/2 cup (120 g) sour cream
- 1/2 cup (120 g) mayonnaise
- 2 tablespoons (30 ml) prepared horseradish (not cream-style, for more kick)
- 1 teaspoon (5 ml) Dijon mustard
- 1 teaspoon (5 ml) white wine vinegar
- 1/4 teaspoon salt, plus more to taste
- 1/8 teaspoon black pepper
For the Tangy Mustard Sauce (makes about 3/4 cup / 180 ml):
- 1/4 cup (60 g) Dijon mustard
- 2 tablespoons (30 ml) honey
- 2 tablespoons (30 ml) apple cider vinegar
- 1/4 cup (60 ml) olive oil
- 1 small shallot, minced (about 1 tablespoon / 15 ml)
- Pinch of salt and pepper
For the Sweet Bourbon Glaze (makes about 1/2 cup / 120 ml):
- 1/4 cup (60 ml) bourbon
- 1/4 cup (60 ml) brown sugar, packed
- 2 tablespoons (30 ml) soy sauce
- 1 tablespoon (15 ml) Dijon mustard
- 1 clove garlic, minced
For the Garlic Aioli (makes about 1/2 cup / 120 ml):
- 1/2 cup (120 g) mayonnaise
- 1 clove garlic, grated or minced
- 1 teaspoon (5 ml) lemon juice
- 1/2 teaspoon Dijon mustard
- Pinch of salt
For the Spicy Chipotle Mayo (makes about 1/2 cup / 120 ml):
- 1/2 cup (120 g) mayonnaise
- 1–2 chipotle peppers in adobo sauce, minced (adjust to taste)
- 1 teaspoon (5 ml) adobo sauce from the can
- 1 teaspoon (5 ml) lime juice
- Pinch of salt
Instructions
- Classic Creamy Horseradish Sauce: In a small bowl, whisk together sour cream, mayonnaise, horseradish, Dijon mustard, white wine vinegar, salt, and pepper. Taste and adjust seasoning. Cover and refrigerate for at least 15 minutes to let the flavors meld.
- Tangy Mustard Sauce: In a small bowl, whisk together Dijon mustard, honey, apple cider vinegar, olive oil, minced shallot, salt, and pepper. Let sit at room temperature for 10 minutes before serving.
- Sweet Bourbon Glaze: In a small saucepan over medium heat, combine bourbon, brown sugar, soy sauce, Dijon mustard, and garlic. Bring to a gentle simmer, then reduce heat to low. Cook for 5–7 minutes, stirring occasionally, until thickened and reduced by about half. Remove from heat and let cool slightly. This glaze can be brushed on the cooked pork slices or drizzled over the sandwich.
- Garlic Aioli: In a small bowl, stir together mayonnaise, grated garlic, lemon juice, Dijon mustard, and salt. Let sit for 5 minutes before using to allow the garlic flavor to infuse.
- Spicy Chipotle Mayo: In a small bowl, combine mayonnaise, minced chipotle peppers, adobo sauce, lime juice, and salt. Adjust the amount of chipotle to your heat preference. Refrigerate until ready to use.
- For the sandwich: Slice cooked pork tenderloin (cooked to 145°F / 63°C as per USDA FSIS safe minimum, then rested 3 minutes) thinly against the grain. Spread your chosen sauce on both sides of a toasted bun or bread. Pile the pork slices on, add any additional toppings like lettuce, tomato, or caramelized onions, and serve immediately.
Tips
- Substitutions: For the horseradish sauce, you can use Greek yogurt instead of sour cream for a lighter version. If you don’t have bourbon, use apple juice or chicken broth mixed with a splash of vanilla extract—it won’t be the same, but it will add a sweet note. For the aioli, if you don’t have fresh garlic, use 1/4 teaspoon garlic powder.
- Make ahead: All of these sauces can be made 1–2 days in advance and stored in the refrigerator. The flavors actually improve after a few hours. Bring them to room temperature before serving for best taste.
- Consistency: If a sauce is too thick, thin it with a teaspoon of water, milk, or extra vinegar. If it’s too thin, add a little more mayonnaise or sour cream.
- Common mistake: Adding too much horseradish or chipotle can overpower the pork. Start with less and taste as you go. You can always add more, but you can’t take it out.
Serving Suggestions
These sauces are perfect on a pork tenderloin sandwich served on a toasted brioche bun or a crusty baguette. Add crisp lettuce, sliced tomato, and red onion for crunch. For a heartier meal, serve with sweet potato fries, coleslaw, or a simple green salad. The creamy horseradish sauce pairs beautifully with roasted pork, while the bourbon glaze is excellent with grilled pork and pairs well with pickled vegetables.
Variations
- Herbed Cream Sauce: Add 1 tablespoon of chopped fresh chives, parsley, or dill to the horseradish sauce for a fresh, green flavor.
- Smoky BBQ Sauce: Mix 1/2 cup (120 ml) of your favorite BBQ sauce with 1 teaspoon of liquid smoke and 1 tablespoon of apple cider vinegar. Brush on the pork while grilling.
- Apple and Sage Sauce: Simmer 1 cup (240 ml) apple cider with 1 tablespoon of fresh sage leaves until reduced by half, then stir in 2 tablespoons of butter. This is a fall-inspired twist.
- Spicy Honey Mustard: Add 1 teaspoon of hot sauce or a pinch of cayenne to the mustard sauce for extra heat.
Storage and Reheating
Store any leftover sauce in an airtight container in the refrigerator. The creamy sauces (horseradish, aioli, chipotle mayo) will keep for up to 4 days. The mustard sauce and bourbon glaze will keep for up to 1 week. Stir well before serving. The bourbon glaze can be reheated in a small saucepan over low heat or in the microwave in 15-second intervals. Do not freeze sauces containing mayonnaise, as they will separate when thawed.
Frequently Asked Questions
Can I use these sauces on other meats? Absolutely! The horseradish sauce is fantastic on roast beef, the mustard sauce works well with chicken, and the bourbon glaze is great on salmon or even grilled vegetables.
How do I make the sauce less spicy? For the horseradish sauce, use cream-style horseradish instead of prepared. For the chipotle mayo, start with just 1 teaspoon of minced chipotle and omit the adobo sauce. You can also add a teaspoon of honey to balance the heat.
What if I don’t have fresh garlic? Use 1/4 teaspoon of garlic powder per clove. Rehydrate it in a teaspoon of water for a few minutes before adding to the sauce.
Can I make these sauces vegan? Yes, use vegan mayonnaise and sour cream alternatives. For the bourbon glaze, ensure your brown sugar is vegan (most are). The mustard sauce is naturally vegan if you use a vegan-friendly honey substitute like maple syrup.
How long can I keep the sauces at room temperature? Per food safety guidelines, do not leave any sauce containing mayonnaise or dairy out for more than 2 hours. The mustard sauce (without dairy) can sit out for up to 4 hours, but it’s best to refrigerate if not using immediately.
Can I use these sauces as a marinade instead? The mustard sauce and bourbon glaze can double as a marinade, but do not reuse marinade that has touched raw pork. If you want to use it as a finishing sauce, set aside a portion before adding the raw meat.
