Step-by-Step Instructions
1. Prepare the Potatoes
- Preheat oven to 400°F (200°C).
- Wash and scrub potatoes thoroughly. Pat dry.
- Pierce each potato with a fork 4–5 times.
- Rub with olive oil, garlic powder, salt, and pepper.
2. Wrap in Foil
- Place each potato on a foil sheet and wrap tightly.
- For crispier skin, leave a small gap at the top instead of sealing fully.
3. Bake
- Place wrapped potatoes directly on the oven rack.
- Bake for 50–60 minutes (depending on size) until tender when pierced with a fork.
- For grilling: Place on medium heat for 45–60 minutes, turning occasionally.
4. Make the Parmesan Ranch Sauce
- In a medium bowl, combine mayonnaise, sour cream, Parmesan, milk, lemon juice, and ranch mix.
- Whisk until smooth and creamy.
- Adjust thickness with more milk if desired.
- Stir in fresh herbs.
5. Assemble & Serve
- Slice baked potatoes open, fluff with a fork, and drizzle generously with Parmesan Ranch Sauce.
- Garnish with extra Parmesan, chives, or crispy bacon bits.
Cooking Variations
- Air Fryer Method: Bake at 390°F (200°C) for 40–45 minutes (without foil for crispier skin).
- Campfire Method: Wrap potatoes in double foil and place in hot coals for 45–60 minutes.
- No-Foil Method: Rub potatoes with oil, place directly on oven rack, and bake uncovered for crisp skin.
Serving Suggestions
- Pair with grilled steak, roasted chicken, or salmon.
- Serve alongside BBQ ribs or burgers at cookouts.

- Turn into a loaded baked potato bar for parties.

Pro Tips for Success
- Use Russet Potatoes for the fluffiest texture.

- Don’t Over-Mix Sauce – whisk gently to keep it creamy.
- Crispier Skin Trick: Unwrap potatoes for the last 10 minutes of baking.
