(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Directions

  1. Preheat Oven: Set your oven to 400°F (200°C) and grease a muffin tin.

  2. Prepare Wet Ingredients: In a mixing bowl, beat the eggs and mix in the sour cream until well combined.

  3. Add Cheeses and Chives: Stir in the shredded cheddar cheese, Parmesan cheese, chopped chives, and a pinch of salt.

  4. Incorporate Mashed Potatoes: Gently fold in the mashed potatoes, ensuring the mixture is evenly combined.

  5. Fill Muffin Tin: Spoon the mixture into the greased muffin tin, filling each cup to the top.

  6. Bake: Bake in the preheated oven for about 20-25 minutes, or until the tops are golden brown and puffed up.

  7. Cool and Serve: Allow the potato puffs to cool slightly before carefully removing them from the muffin tin.

Servings and Timing

  • Servings: 12 puffs (1 tray)

  • Prep Time: 10 minutes

  • Cook Time: 20-25 minutes

  • Total Time: 30-35 minutes

Variations

  • Cheese Options: Experiment with different cheeses like gouda, fontina, or Gruyère for varied flavors.

  • Herb Infusion: Add herbs such as parsley, thyme, or rosemary to the mixture for an aromatic twist.

  • Spicy Kick: Incorporate finely chopped jalapeños or a dash of cayenne pepper for heat.

  • Vegan Version: Use dairy-free cheese, plant-based sour cream, and egg replacer to make this recipe vegan-friendly.

Storage/Reheating

  • Refrigeration: Store cooled puffs in an airtight container in the refrigerator for up to 5 days.

FAQs

How can I make these puffs spicier?

Add finely chopped jalapeños or a pinch of cayenne pepper to the mixture before baking.

Can I use instant mashed potatoes?

For the best texture and flavor, it's recommended to use homemade mashed potatoes. Instant mashed potatoes may alter the consistency of the puffs.

Are these puffs suitable for freezing?

Yes, they freeze well. Ensure they are cooled completely before freezing and stored in an airtight container.

Can I use a mini muffin tin for smaller puffs?

Absolutely. Mini muffin tins will yield smaller puffs; adjust the baking time accordingly, checking for doneness after 15 minutes.

How do I prevent the puffs from sticking to the muffin tin?

Grease the muffin tin thoroughly or use muffin liners to prevent sticking.

Can I add vegetables to the mixture?

Yes, finely chopped vegetables like spinach, bell peppers, or mushrooms can be added for added nutrition and flavor.

Are these puffs gluten-free?

To make them gluten-free, substitute the all-purpose flour with a gluten-free flour blend.

How do I know when the puffs are done?

The puffs should be golden brown on top and firm to the touch. A toothpick inserted into the center should come out clean.

Can I use Greek yogurt instead of sour cream?

Yes, Greek yogurt can be used as a substitute for sour cream, offering a tangy flavor and creamy texture.

What can I serve these puffs with?

They pair well with roasted meats, salads, or can be enjoyed on their own as a snack.
