Ingredients

  • 4 servings mashed potatoes
  • 1/4 cup sweet pickle relish, drained
  • 2 tablespoons mayonnaise
  • 1 tablespoon instant minced onion
  • 2 teaspoons prepared mustard
  • 4 to 6 frankfurters

Instructions

  1. Combine mashed potatoes, relish, mayonnaise, minced onion, and mustard in a bowl.
  2. Mix well to incorporate all ingredients.
  3. Spoon the mixture into a 1-quart casserole dish.
  4. Cut each frankfurter in half lengthwise.
  5. Insert frankfurter pieces upright around the edge of the mashed potato mixture.
  6. Bake at 350°F (175°C) for 25 to 30 minutes until heated through and slightly browned.

Tips & Substitutions

For an extra kick, consider adding chopped jalapeños or a sprinkle of cayenne pepper to the mashed potato mixture. You can substitute the frankfurters with turkey or vegan hot dogs for a healthier or plant-based option, respectively. Experiment with different types of mustard, like honey mustard or whole grain, to enhance the flavor profile.

Serving Suggestions

This casserole pairs beautifully with a fresh green salad or steamed vegetables for a complete meal. For added flavor, serve with a side of barbecue sauce or zippy tomato relish. You can also top it with shredded cheese before baking for a cheesy twist.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in a preheated oven at 350°F (175°C) for about 15-20 minutes, or until heated through. You can also microwave individual portions, covering them to retain moisture.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can prepare the casserole in advance and refrigerate it before baking. Just cover it tightly with plastic wrap or aluminum foil. When ready to bake, remove the cover and bake as directed, adding a few extra minutes if it's coming straight from the refrigerator.

What can I use instead of mayonnaise?

If you're looking for a substitute for mayonnaise, you can use Greek yogurt or sour cream for a tangy flavor. For a vegan option, try using a plant-based mayo or mashed avocado to keep the creamy texture without dairy.

How do I ensure the mashed potatoes are smooth?

To achieve smooth mashed potatoes, ensure you mash them while they're still warm and use a potato ricer or food mill if possible. Adding a splash of milk or cream can also help achieve a creamier consistency. Avoid over-mixing, as this can make them gluey.
