How do I store leftover Cajun Hot Dog Sliders with Spiced Mustard?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep mini hot dogs from drying out.

Can I substitute ingredients in Cajun Hot Dog Sliders with Spiced Mustard?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Cajun Hot Dog Sliders with Spiced Mustard for a different number of people?
