Ingredients (notes only)

Potatoes & Aromatics

  • Yukon Golds (or russets): Yukon = creamier, russets = starchier/thicker sauce.
  • Onion + garlic: Sweet base; mince to keep sauce smooth.
  • Fresh thyme + pinch nutmeg: Savory balance without heaviness.

Sauce (lactose-free)

  • Butter (or lactose-free butter), flour for a light roux (or cornstarch slurry for gluten-free).
  • Lactaid 2% milk + low-sodium broth: silky, pourable cream.
  • Salt/pepper: Season boldly—potatoes mute flavor.

Optional Cheese

  • Lactose-free cheddar or Gruyère (many aged cheddars are naturally lactose-free). Parmesan for browning.

Finish

  • Chopped parsley/chives; lemon zest for brightness.

Step-by-Step (6–8 concise steps)

  1. Prep: Heat oven 375°F/190°C. Grease a 9×13-in (3-qt) dish. Slice potatoes ⅛ in (3 mm); keep submerged in cold water, then pat dry.
  2. Roux: Melt 3 Tbsp butter in saucepan; sauté 1 small minced onion 3–4 min. Stir in 3 Tbsp flour 1 min.
  3. Sauce: Whisk in 3 cups Lactaid milk + 1 cup broth, 3 minced garlic, 1 tsp salt, ½ tsp pepper, ½ tsp thyme, pinch nutmeg. Simmer gently 3–5 min to nappe (don’t boil).
  4. Layer: Shingle half the potatoes in dish, season lightly. Pour over half the sauce. Repeat. Top with ¾ cup lactose-free cheddar if using.
  5. Bake covered: Tightly foil; bake 40–45 min until potatoes are mostly tender.
  6. Uncover & brown: Remove foil; sprinkle ¼ cup Parmesan (optional). Bake 20–25 min more until bubbling and golden and a knife slides through easily (target potato center ≈205°F/96°C).
  7. Rest: Stand 10–15 min to set for clean slices.
  8. Finish: Garnish with parsley/chives; zest lemon lightly if desired.

Pro Tips

  • Warm dairy, gentle simmer: Keeps Lactaid smooth—avoid a rolling boil.
  • Even slices = even bake: Use a mandoline (gloves!) for ⅛-inch slices.
  • Season in layers: A pinch of salt/pepper on each potato layer = brighter flavor.
  • Make-ahead: Par-bake covered 40–45 min; cool, cover, refrigerate up to 48 h. Day-of: add cheese/topping, bake 20–30 min uncovered to finish and brown.

Variations (mapped to interests)

  • Fiesta Party Scalloped Potatoes: Stir 1–2 roasted jalapeños, ½ tsp chili powder, and 1 cup pepper-jack (lactose-free) into top layer; finish with cilantro. (Fiesta Party)
  • Herb-Parmesan: Extra thyme + rosemary; Parmesan crisp on top. (Good Eats)
  • Vegan Option (for guests): Use oat milk, vegan butter, and 2 Tbsp nutritional yeast + ½ cup cashew cream; skip cheese. (Vegane Rezepte – variation only)
  • Lighter: Half milk/half broth; no cheese; add extra herbs.
  • Gluten-free: Replace flour with 2½ Tbsp cornstarch mixed into cold Lactaid; simmer to thicken.

How to Serve

With roast turkey, chicken, ham, or steak; at Thanksgiving Dinner and Holiday tables. Pair with a crisp salad—or serve alongside herbed quinoa for a balanced plate. (Quinoa)

Make Ahead & Storage

  • Fridge: 4 days, covered.
  • Reheat: 325°F/165°C, covered 15–25 min until hot and saucy; add a splash of milk if thick.
  • Freeze: Not ideal—potatoes soften. If needed, freeze par-baked portions up to 1 month; thaw overnight and finish in oven.

FAQs

Will Lactaid curdle? No if thickened and gently heated; avoid boiling and use a roux/slurry.
Best potato? Yukon Gold for creamy slices; russet for thicker sauce.
Can I use only milk (no broth)? Yes—use 4 cups Lactaid; season a touch more.
Slow cooker? Assemble in crock; cook LOW 4–5 h until tender, then broil top in oven to brown.
