Swaps for unsalted butter
Instead of butter
- Salted butter: The same amount, with about ¼ tsp less salt per stick (½ cup) elsewhere in the recipe. Nothing noticeable once you cut the salt.
- Plant-based butter sticks: The same amount. The closest swap.
- Refined coconut oil: The same amount: solid when the butter is soft or cold, melted when it is melted. It is all fat, so bakes are a bit more tender and rich, with no butter flavor.

Swaps for onion
Instead of onion
- Another onion: The same amount. Yellow is the all-rounder; white is sharper and crisper; red is milder raw and adds color; sweet onions are mildest.
- Shallots: The same amount, chopped. Milder and sweeter, with a hint of garlic.
- Leeks: About 1½ times as much, white and light green parts. Milder and softer when cooked.
Swaps for garlic
Instead of garlic
- Garlic powder: ⅛ tsp for each clove. Mellower and sweeter, with no bite.
- Jarred minced garlic: ½ tsp for each clove. Milder and slightly sour from the preserving liquid.
Swaps for all-purpose flour
Instead of all-purpose flour
- Gluten-free 1:1 baking flour: The same amount, a blend that includes xanthan gum. A little grittier and more crumbly, browns faster and dries out sooner.
- Bread flour: The same amount. More gluten: chewier cookies and bread, tougher cakes.
- Whole wheat flour: Up to half of the flour. Nuttier, darker and denser.

Swaps for whole milk
Instead of milk
- Unsweetened soy milk: The same amount. The closest plant milk for baking: its protein helps things brown and set.
- Unsweetened oat milk: The same amount. Creamy and mild with a hint of sweetness.
- Unsweetened almond milk: The same amount. Thinner and less rich, so cakes are a little paler and drier.

Swaps for heavy cream
Instead of heavy cream
- Half-and-half: The same amount. Thinner and less rich.
- Milk + melted butter: ¾ cup whole milk + ¼ cup melted butter for each cup. Close in richness for cooking and baking, but it won't whip.
- Full-fat coconut milk: The same amount. Rich and silky with a coconut taste.

Swaps for kosher salt
Instead of salt
- Table salt or fine sea salt: About half as much as Diamond Crystal kosher, about ¾ as much as Morton kosher. The same saltiness when measured this way.
- Salt by weight: 1 tsp is about 6 grams of table salt, 5 grams of Morton kosher, 3 grams of Diamond Crystal kosher. The most reliable way to swap, especially in baking and brines.
Swaps for ground nutmeg
Instead of nutmeg
- Ground mace: A little less. Made from the same fruit; slightly sharper.
- Pumpkin pie spice or allspice: The same amount. Warmer and more cinnamon-forward.
Swaps for fresh thyme leaves
Instead of thyme
- Dried thyme: 1 tsp dried for each 1 tbsp chopped fresh (a third as much). Earthier and a little less bright, but dried thyme holds up well in soups, stews and roasts.
- Fresh oregano or marjoram: The same amount. Oregano is stronger; marjoram is sweeter and milder.
- Fresh rosemary: Half as much. Piney and stronger.
Swaps for fresh parsley
Instead of parsley
- Dried parsley: 1 tsp dried for each 1 tbsp chopped fresh (a third as much). Very mild; it adds color more than flavor.
- Cilantro: The same amount. Stronger and citrusy; suits Mexican and Asian dishes.
- Celery leaves or chervil: The same amount. Celery leaves are peppery and grassy; chervil is mild with a hint of anise.
Step 1 of 11
Heat the oven to 375°F (190°C) and a 9x13-inch baking dish.
butter (how to grease and flour a pan)
Grease and flour a pan Coat a pan with fat (and sometimes flour) so baked goods release cleanly. 1. Rub a thin layer of soft butter or shortening into every corner with a paper towel, or use baking spray.2. For cakes, add a spoonful of flour, tilt and tap the pan until it is coated.3. Turn the pan over and tap out the extra flour.4. For chocolate cakes, use cocoa instead of flour so there is no white film. Done when: Every surface, corners included, is lightly coated with no bare spots or thick clumps. How to grease and flour a baking pan: mistakes to avoid375°F

Peel the potatoes and them about 1/8 inch thick with a sharp knife or a mandoline. Don't rinse the slices; their starch helps thicken the sauce.
slice (how to slice)
Slice Cut food into flat pieces of the same thickness. 1. Give round food a flat side to sit on.2. Hold it with your fingertips curled under.3. Cut with long strokes, pushing the knife forward and down rather than straight down.4. Move your guiding hand back the same distance each time so every slice matches. Done when: The slices are even. For meat, slicing across the grain (across the lines of muscle) gives the tenderest bite. Safety: Keep the fingertips of your guiding hand curled under, knuckles toward the blade, and set the board on a damp towel so it can't slide. Slice hot roasts on a board with a groove for the juices.How to slice evenly: mistakes to avoidStep 3 of 11
Melt the butter in a large saucepan over medium heat. Add the onion and .
cook until soft but not browned (how to sweat (vs. sauté))
Sweat (vs. sauté) Cook vegetables gently in a little fat so they soften and turn sweet without browning. Sautéing uses higher heat to brown them. 1. Melt a spoonful of butter or warm oil over medium-low heat.2. Add the onions or other vegetables and a pinch of salt, which draws out their water.3. Stir every couple of minutes; a lid for the first few minutes helps.4. Turn the heat down if you see any browning. Done when: The vegetables are soft and see-through at the edges, with no brown color. Onions take 8 to 10 minutes. How to sweat onions (vs. sautéing): mistakes to avoidStep 4 of 11
Stir in the garlic until fragrant.
Step 5 of 11
Whisk (how to whisk)
Whisk Beat ingredients with a whisk to mix them smoothly or to add air. 1. Use a bowl big enough to whisk without splashing; set it on a damp towel to stop it spinning.2. Hold the whisk loosely and move it in quick circles or side to side, touching the bottom.3. For lumpy mixtures, add liquid a little at a time and whisk after each.4. For sauces on the stove, keep the whisk moving across the whole bottom of the pan. Done when: The mixture is even with no lumps or streaks of egg. How to whisk: mistakes to avoidStep 6 of 11
Slowly in the milk and cream, then add the salt, pepper, nutmeg and thyme.

Simmer (how to simmer)
Simmer Cook liquid just below a boil, with small bubbles breaking the surface now and then. 1. Bring the liquid up over medium-high heat.2. As soon as bubbles rise steadily, turn the heat down.3. Adjust until only a few small bubbles break the surface every second or two.4. Stir now and then and check that it hasn't crept back to a boil. Done when: You see lazy, small bubbles, not a rolling boil. A "bare" simmer has just a bubble here and there. Safety: Steam burns fast: lift lids and foil away from your face, tipping the far edge up first.How to simmer: mistakes to avoidwhisking (how to whisk)

Layer a third of the potato slices in the dish, overlapping them like shingles, and pour a third of the sauce over them. Repeat twice, pressing the top layer down so it's mostly under the sauce.
Step 9 of 11
Cover the dish tightly with foil, set it on a sheet pan to catch drips and bake.

Uncover and bake until the top is golden brown and a knife slides through the center with no resistance.

Let it so the sauce thickens, then sprinkle with parsley and serve.
rest (how to rest)
Rest Leave cooked meat, baked goods or dough alone for a while before you cut, slice or shape it. 1. Move meat to a board or plate as soon as it is done (a few degrees shy of target for big roasts; it keeps rising).2. Tent it loosely with foil if the kitchen is cool.3. Rest steaks and chops 5 minutes, roasts 15 to 20, a turkey 30.4. For dough, cover it so it doesn't dry out while it relaxes. Done when: Meat juices stay in when you slice; dough rolls out without springing back. Safety: Rest at room temperature for under an hour, then refrigerate leftovers within 2 hours of cooking.How to rest meat and dough: mistakes to avoidAll done
