Ingredients
- 1 ½ lb yukon gold potatoes, halved, or quartered if large
- 1 lb carrots, peeled, cut into 2-inch pieces
- 1 onion, cut into wedges
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.
- 3 lb boneless beef chuck roast
- 1 ½ tsp kosher salt
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.
- ¾ tsp black pepper
- 1 tbsp vegetable oil
Swaps for vegetable oil
Instead of vegetable oil
- Another neutral oil: The same amount. No difference.
- Melted butter: The same amount. Richer, buttery flavor; cakes are a little less moist and firmer once cool.
- Light olive oil: The same amount. "Light" olive oil tastes mild.
- 1 cup beef broth
Swaps for beef broth
Instead of broth
- Vegetable broth: The same amount. Lighter and slightly sweeter.
- Chicken broth: The same amount. Richer and more savory; not vegetarian.
- Bouillon cube, powder or paste + water: Follow the label for the amount of liquid. Close in flavor; a little saltier.
- 2 tbsp tomato paste
Swaps for tomato paste
Instead of tomato paste
- Tomato sauce or passata: 3 tbsp for each 1 tbsp paste. Lighter, fresher tomato flavor.
- Ketchup: The same amount. Sweeter and vinegary; fine for a tablespoon or two.
- 1 tbsp worcestershire sauce
Swaps for worcestershire sauce
Instead of Worcestershire sauce
- Soy sauce + vinegar: 1 tbsp soy sauce + ¼ tsp vinegar + a pinch of sugar for each 1 tbsp. Savory and tangy, less complex.
- Vegan Worcestershire: The same amount. Very close, with no anchovies.
- 3 cloves garlic, minced
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.
- 1 tsp dried thyme
Swaps for dried thyme
Instead of thyme
- Fresh thyme: 1 tbsp chopped fresh for each 1 tsp dried (three times as much). Brighter and more lemony.
- Italian seasoning or dried marjoram: The same amount. Close; Italian seasoning adds oregano and basil.
- 1 bay leaf
- 2 tbsp cornstarch
Swaps for cornstarch
Instead of cornstarch
- All-purpose flour: 2 tbsp flour for each 1 tbsp cornstarch. Sauces turn cloudy instead of glossy and a bit heavier.
- Arrowroot: The same amount. Very clear and glossy; can turn slimy in dairy sauces.
- Potato starch: The same amount. Thickens fast with a clear gloss; don't boil it long.

season (how to season to taste)
Season to taste Add salt (and pepper or acid) bit by bit, tasting as you go, until the food tastes fully of itself. 1. Season meat and vegetables before cooking, holding the salt high so it falls evenly.2. Taste the dish near the end with a clean spoon.3. If it tastes flat, add a pinch of salt, stir and taste again.4. If it tastes heavy or dull, a squeeze of lemon or a splash of vinegar brightens it.5. Stop when another pinch wouldn't make it better. Done when: The flavors are clear and bright, not flat and not salty. Safety: Don't taste dishes that hold raw meat, poultry or eggs; season them by the recipe's amounts and adjust after cooking.How to season to taste: mistakes to avoid - Heat the oil in a large skillet over medium-high heat until it shimmers.
- ⏱ Brown roast: 8 minthe roast well on both sides. It won't cook through; this is for flavor.
Brown (how to brown)
Brown Cook food in a hot pan until its surface turns brown, which adds rich, roasted flavor. 1. Pat the food dry; for ground meat, let the pan get hot first.2. Add a little oil and spread the food in one layer.3. Leave it alone for a few minutes so the bottom browns, then turn or break it up.4. Work in batches if it won't fit in one layer.5. Pour off extra fat if the recipe says to. Done when: Most surfaces are brown, not gray, and the bottom of the pan has browned bits (they are flavor, not burn). Safety: Hot oil spatters: dry the food first, lay it in the pan moving away from you, and keep a lid nearby. Never put water on an oil fire; slide the lid over it and turn off the heat. Browned outside doesn't mean cooked inside: ground beef needs 160°F, poultry 165°F.How to brown meat and vegetables: mistakes to avoid - Set the roast on top of the vegetables in the slow cooker.
- the broth, tomato paste, Worcestershire, garlic and thyme in the hot skillet,
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 avoid, then pour it over the roast. Tuck in the bay leaf.scraping up the browned bits (how to deglaze)
Deglaze Pour liquid into a hot pan and scrape up the browned bits stuck to the bottom, which hold a lot of flavor. 1. After browning, pour off all but a spoonful of fat.2. With the pan still hot, pour in wine, broth or water; it will sizzle and steam.3. Scrape the bottom with a wooden spoon or flat spatula until the brown layer dissolves.4. Let it bubble down, as the recipe says, into the base of a sauce. Done when: The bottom of the pan is clean and the liquid has turned brown and tasty. Safety: Take the pan off the flame before pouring in wine or spirits, and turn your face away from the steam.How to deglaze a pan: mistakes to avoid - Cover and cook on LOW (or 5 to 6 hours on HIGH) until the beef pulls apart easily with a fork. It will be well past the safe 145°F (63°C).⏱ Slow cook (LOW): 8 hr
- Move the beef and vegetables to a platter and cover with foil. Throw away the bay leaf.
- Skim the fat off the liquid and pour the liquid into a saucepan. Bring it to aover medium heat.
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 avoid - Stir the cornstarch and water together, whisk it in and simmer until thickened.⏱ Thicken gravy: 2 min
- Pull the beef into chunks and serve with the vegetables and gravy.

Tips
- Putting the vegetables on the bottom keeps them in the liquid so they cook through.
- Resist lifting the lid; each peek adds cooking time.
- Braised beef is safe at 145°F, but chuck only turns tender once it goes much higher (around 200°F), so cook it by tenderness, not by the thermometer.
- Use a separate cutting board for raw meat, and wash hands, boards and knives in hot soapy water after handling it.
Storage
Refrigerate in an airtight container within 2 hours, up to 4 days. Store the beef in its gravy. Freeze up to 3 months.
