Perfect! Here’s the ultimate science-backed oven-baked steak fries recipe for maximum crispiness and flavor—no deep-frying required.
Crispy Oven-Baked Steak Fries (Food Science Optimized)
Yield: 2–4 servings | Prep: 15 min (+ soaking) | Cook: 30–40 min
Ingredients
- 2 large Russet potatoes (high starch = crispier)
- 1 tbsp cornstarch (key for crunch)
- 2 tbsp high-smoke-point oil (avocado, peanut, or refined olive oil)
- ½ tsp baking soda (alkaline for texture boost)
- 1 tsp salt (plus more to taste)
- Optional seasonings: Garlic powder, smoked paprika, black pepper
Step-by-Step Method (Science-Enhanced)
1. Cut & Soak (Remove Excess Starch)
- Scrub potatoes (leave skin on for texture).
- Cut into ½–¾ inch thick wedges (uniform size = even cooking).
- Soak in cold water + 1 tsp vinegar (or salt) for 30+ min (removes starch, prevents gumminess).
2. Par-Cook (Softens Interior, Rough Surface for Crisp)
- Preheat oven to 425°F (220°C) with a baking sheet inside (hot start = better sear).
- Drain potatoes, then simmer in water + ½ tsp baking soda for 5 min (alkaline weakens pectin, creating a craggy surface).
- Drain well, pat extremely dry (critical for browning).
3. Coat for Maximum Crisp
- Toss dried wedges with:
- 1 tbsp cornstarch (absorbs moisture, adds crunch)
- 2 tbsp oil (even coating promotes Maillard reaction)
- 1 tsp salt + seasonings
4. Bake Like a Pro
- Arrange fries on preheated baking sheet (single layer, spaced apart).
- Bake 25 min, flip, then bake 10–15 min until deep golden.
- For extra crispness, broil 1–2 min (watch closely!).
5. Season & Serve
- Sprinkle with flaky salt right out of the oven.
- Serve with aioli, ketchup, or spicy mayo.
Why This Works: Science Breakdown
✅ Cornstarch absorbs surface moisture, creating a crispier crust.
✅ Baking soda alters potato’s surface texture (like Kenji’s roasted potatoes).
✅ Preheated sheet + oil ensures fast heat transfer for browning (Maillard reaction).
✅ Single layer + flipping prevents steaming = even crispness.
Air Fryer Variation
- Follow steps 1–3, then air fry at 400°F (200°C) for 15–20 min, shaking halfway.
These fries are golden, crunchy outside, and fluffy inside—no fryer needed! Want to tweak the seasoning or try a spicy version? 🔥
