your question can you freeze dauphinoise potatoes before cooking

Dauphinoise potatoes, also known as gratin dauphinois, is a classic French dish of thinly sliced potatoes baked in a creamy garlic sauce. It’s a real crowd pleaser and comfort food favorite in many households. But it’s also a dish that requires some time and effort to prepare. This leads many home cooks to wonder – can you freeze dauphinoise potatoes before cooking?

Freezing Uncooked Dauphinoise Potatoes

The short answer is yes, you can absolutely freeze uncooked dauphinoise potatoes before baking. This is a great way to get a head start on this indulgent dish and have it ready to pop in the oven whenever you need it.

Here are some tips for successfully freezing uncooked dauphinoise potatoes:

1. Choose the Right Potatoes

Go for thicker, waxy potatoes like Russet or Yukon Gold. Thinner potatoes may turn mushy when frozen and thawed. The sturdier texture of thick-cut spuds makes them ideal for freezing.

2. Partially Cook the Potatoes

Potatoes should be partially cooked before freezing, as this helps them better withstand the freezing process. Parboil the sliced potatoes for 5-7 minutes until just underdone. Drain well and allow to cool completely before assembling and freezing.

3. Prepare the Garlic Cream Sauce

Make the creamy garlic sauce for the dauphinoise but allow it to fully cool before using it to layer the potatoes. This prevents separation or curdling when frozen.

4. Layer in Freezer-Safe Container

In a buttered freezer-safe baking dish, layer the cooled parboiled potatoes and garlic cream sauce until you have built the full dauphinoise. Make sure potatoes are submerged in the sauce.

5. Cover Tightly

Wrap the assembled dauphinoise very well in plastic wrap, then foil, to prevent freezer burn. Affix a label with baking instructions.

6. Freeze Immediately

Freeze the wrapped dauphinoise right away until solidly frozen, at least 12 hours. Transfer to a freezer bag if storing for more than 1 month.

7. Thaw in Fridge

When ready to use, thaw the frozen dauphinoise slowly in the refrigerator overnight. This helps prevent separation of the potatoes and sauce.

8. Bake as Usual

Bake directly from frozen at 375°F for 50-60 minutes, until hot and bubbly. Let stand 10 minutes before serving. Enjoy!

Tips for Freezing Dauphinoise Potatoes

Follow these handy tips for best results when freezing uncooked dauphinoise potatoes:

  • Choose firm, starchy potatoes – this prevents mushiness.
  • Don’t overfill layers – leave some space between potato slices for even cooking.
  • Make sure potatoes are fully submerged in sauce before freezing to prevent oxidation.
  • Let the assembled dauphinoise chill in the fridge before freezing, to help flavors meld.
  • Press plastic wrap down onto surface of the dauphinoise to prevent freezer burn.
  • Use within 2-3 months for best quality and taste.
  • Thaw slowly in the refrigerator before cooking.
  • Add 10-15 minutes to the normal baking time after freezing.
  • Check center is piping hot before serving.

What Happens When You Freeze Raw Dauphinoise Potatoes

Freezing uncooked dauphinoise potatoes allows you to enjoy this comfort food favorite without all the last minute preparation. But just what effect does freezing have? Here’s what happens:

  • Texture changes slightly – potatoes become softer.
  • Loss of some moisture, concentrating flavors.
  • Garlic cream sauce thickens up.
  • Needs extended baking time to heat through frozen center.
  • Increased melting together of sauce and potatoes.
  • Potential damage to cell structure if frozen too quickly.
  • Risk of oxidation of potatoes if not fully submerged.
  • Can lose some richness of flavor during thawing process.

The changes are quite subtle, and freezing certainly doesn’t ruin the dish. With proper freezing methods, you can look forward to a hearty dauphinoise with concentrated flavors after freezing.

Difference Between Raw and Baked Dauphinoise

How does freshly assembled, uncooked dauphinoise differ from a baked version you are freezing? Here are some key differences:

Raw Dauphinoise

  • Potatoes are still quite firm and toothsome.
  • Garlic cream sauce is thick and custard-like.
  • Distinct layers of potato slices and sauce.
  • Raw garlic flavor predominates.
  • Parmesan topping not yet melted and browned.

Baked Dauphinoise

  • Potatoes become very tender and meld with sauce.
  • Sauce melts into a thin, silky texture.
  • Potatoes merge together into a rich gratin.
  • Baked garlic flavor is much milder, blended.
  • Crispy, browned cheese topping.

The textures transform significantly between the raw assembled and baked dish. Freezing uncooked maintains the integrity of layers better. Baking melds everything together into an ultra smooth, integrated gratin.
