Seasoning a measuring spoon means applying a thin layer of oil and heating it to create a non-stick, rust-resistant coating. This is essential for carbon steel and cast iron spoons, but not for stainless steel or plastic. To season, wash and dry the spoon completely, coat it with a high-smoke-point oil like flaxseed or grapeseed, then bake it upside down in a 400°F oven for one hour. Let it cool inside the oven. This creates a polymerized layer that protects the metal and improves release for sticky ingredients like honey or molasses.

Quick Answer

Seasoning a measuring spoon protects it from rust and makes it non-stick. Only carbon steel and cast iron spoons need seasoning. Use a high-smoke-point oil and bake at 400°F for an hour. Re-season if the spoon looks dull or rusty. Avoid soap when cleaning seasoned spoons.

  • What does seasoning do?: Seasoning creates a polymerized oil layer that prevents rust and makes the spoon non-stick.
  • Which spoons need seasoning?: Only carbon steel and cast iron measuring spoons. Stainless steel and plastic don’t need it.
  • What oil should I use?: Use flaxseed, grapeseed, or canola oil. Avoid olive oil or butter as they smoke too low.
  • How long does seasoning last?: It lasts for many uses but may need re-seasoning if the spoon develops rust or loses its non-stick feel.
  • Can I season a spoon in a skillet?: Yes, you can heat the oiled spoon on a stovetop over medium heat for 5-10 minutes, but oven baking is more even.

Why Season a Measuring Spoon?

Seasoning transforms raw metal into a durable, non-stick surface. For carbon steel and cast iron measuring spoons, it’s the difference between a spoon that rusts after one wash and one that lasts for years. The oil bonds to the metal at high heat, filling microscopic pores and creating a smooth coating. This prevents sticky ingredients like corn syrup or peanut butter from clinging, and it blocks moisture that causes rust.

Stainless steel spoons don’t need seasoning because they’re already rust-resistant and naturally non-porous. Plastic spoons can’t be seasoned because they’d melt. So check your spoon’s material—if it’s carbon steel or cast iron, seasoning is a must.

Materials Needed for Seasoning

  • Measuring spoon (carbon steel or cast iron)
  • Dish soap and scrub brush (for initial cleaning)
  • High-smoke-point oil: flaxseed, grapeseed, canola, or vegetable oil
  • Paper towel or lint-free cloth
  • Baking sheet and aluminum foil (optional, for drip catch)
  • Oven (or stovetop skillet)

Flaxseed oil is the best choice because it polymerizes hard and fast, but it can be expensive. Grapeseed oil is a great budget-friendly alternative with a smoke point of 420°F. Avoid extra-virgin olive oil (smoke point ~375°F) and butter (350°F); they’ll burn and leave sticky residue.

Step-by-Step Seasoning Process

  1. Wash thoroughly: Scrub the spoon with hot soapy water to remove any factory oils or residue. Rinse and dry completely with a towel.
  2. Apply oil: Pour a few drops of oil onto the spoon. Use a paper towel to rub it all over—inside the bowl, the handle, and the edges. Then wipe off the excess so the spoon looks almost dry, just slightly shiny. Too much oil will pool and create a sticky coating.
  3. Bake upside down: Place the spoon on a baking sheet lined with foil. Put it in a cold oven, then set the oven to 400°F. Bake for one hour. The upside-down position allows any excess oil to drip off.
  4. Cool in oven: Turn off the heat and let the spoon cool inside the oven for at least an hour. This prevents thermal shock and helps the coating harden.
  5. Repeat for extra layers: For a more durable finish, repeat the oiling and baking process 2-3 times. Each layer adds thickness and protection.

If you don’t have an oven, you can season on a stovetop: heat a dry cast iron skillet over medium heat, place the oiled spoon in the skillet, and heat for 5-10 minutes, flipping once. Let it cool in the pan.

How to Maintain a Seasoned Spoon

Never use soap on a seasoned spoon—it strips the oil layer. Instead, rinse with hot water and scrub with a non-abrasive sponge. For stuck-on food, boil a little water in a kettle and pour it over the spoon, then scrub gently. Dry the spoon immediately with a towel to prevent rust.

After each wash, apply a tiny drop of oil and rub it in with your fingers. This refreshes the seasoning and keeps the spoon looking dark and shiny. Store the spoon in a dry drawer or hang it away from moisture.

If you notice rust spots or the spoon starts sticking, it’s time to re-season. Scrub off the rust with steel wool, wash, dry, and repeat the full seasoning process.

When Not to Season

Do not season stainless steel or plastic measuring spoons. Stainless steel doesn’t need it—it’s already non-reactive and rust-proof. Seasoning would just create a greasy film that attracts dust and may peel off into food. Plastic spoons will melt at oven temperatures above 300°F, so they can’t be seasoned.

Also avoid seasoning if you only use the spoon for dry ingredients like flour or sugar. Dry measuring doesn’t benefit from a non-stick surface, and the seasoning might wear off quickly from abrasive dry goods.

Pro Tips

  • Use a dedicated spoon for wet ingredients like honey or molasses—season it well, and it will release every drop without waste.
  • If you don’t have flaxseed oil, try walnut or sunflower oil; they have high smoke points and polymerize well.
  • Season multiple spoons at once by placing them on a baking sheet with space between each for air circulation.
  • To test if seasoning is done, run the spoon under cold water—water should bead up and roll off, not wet the surface.

Common Mistakes to Avoid

  • Using too much oil: it pools and creates a sticky, uneven coating that never hardens properly.
  • Washing with soap after seasoning: soap dissolves the oil layer, undoing all your work.
  • Skipping the cool-down phase: taking the hot spoon out can cause the coating to crack from thermal shock.
  • Seasoning a rusty spoon without removing the rust first: the seasoning won’t bond to rust, and the rust will continue to spread underneath.

FAQ

How often should I re-season my measuring spoon?

Re-season when the spoon looks dull, feels sticky, or shows rust spots. With good care, once every few months is enough. If you use it daily for wet ingredients, you might need to re-season every 4-6 weeks.

Can I season a measuring spoon in a toaster oven?

Yes, as long as the toaster oven can maintain 400°F and has enough clearance. Place the spoon on the rack or a tray, but ensure it doesn’t touch the heating elements. Watch it closely because toaster ovens can have hot spots.

Is it safe to use a seasoned spoon with acidic foods?

Avoid prolonged contact with acidic foods like tomato sauce or vinegar, as they can break down the seasoning. A quick dip is fine, but don’t leave the spoon sitting in acidic liquid. Rinse and dry immediately after use.

The Bottom Line

Seasoning your carbon steel or cast iron measuring spoon is a simple, one-time task that pays off with years of reliable, non-stick use. By baking on a thin oil layer, you create a protective barrier that repels rust and makes sticky ingredients slide right off. Just remember to avoid soap, dry promptly, and give it a light oil rub after each wash. With these steps, your spoon will stay in prime condition—no rust, no stick, no fuss.
