Step 1: Preparing the Potatoes

Preheat your oven to 425°F. Wash and peel the potatoes if desired. Cut them into ¼-inch thick strips to ensure even cooking. Rinse the potato strips under cold water to remove excess starch, which helps them crisp up in the oven. After rinsing, pat them dry thoroughly using a clean kitchen towel or paper towels.

Step 2: Seasoning the Fries

In a large mixing bowl, toss the potato strips with olive oil to ensure they are evenly coated. In a small bowl, mix together the powdered cheese, chili powder, cumin, garlic powder, and salt. Sprinkle this seasoning blend over the fries and toss again to distribute the spices evenly.

Step 3: Baking the Fries

Spread the seasoned fries out on a baking sheet lined with parchment paper or lightly greased. Make sure the fries are in a single layer with some space between them to allow proper crisping. Bake in the preheated oven for 35-40 minutes, flipping them halfway through to ensure even browning. The fries are done when they are golden brown and crisp on the edges.

Step 4: Making the Cheese Sauce

While the fries are baking, prepare the cheese sauce. In a small bowl, mix together the Greek yogurt, taco sauce, and powdered cheese until smooth. This sauce can be served warm or cold. If you prefer a warmer sauce, microwave it for 10-15 seconds, stirring in between.

Step 5: Preparing the Salsa Ketchup

Combine the salsa and ketchup in a bowl and stir well. This dipping sauce adds a tangy, slightly spicy kick to the fries.

Step 6: Serving the Fries

Once the fries are golden and crispy, remove them from the oven and let them cool slightly. Serve them immediately with the cheese sauce and salsa ketchup on the side.
