In Jewish life, a kosher kitchen ensures:1. Separation of Meat and Dairy

The Torah repeats the command three times not to mix meat and milk. Over time, this became the foundation of kosher practice.

2. Awareness

Keeping kosher builds mindfulness — you have to pay attention to what you eat and how you prepare it.

3. Sanctifying the Everyday

Kosher laws turn cooking, eating, and cleaning into acts of holiness.

4. Community and Identity

Across the world, kosher kitchens share the same rules. It unites us through generations.

Now let’s walk through the “how.”

PART 1 — Preparing to Kosher Your Kitchen

Before you start the actual koshering process (called kashering), you first need to clean and organize.

Step 1: Remove or Use Up Non-Kosher Items

You can:

finish them,
give them away,
or throw them out.

Step 2: Separate Meat and Dairy

A kosher kitchen has two sets of:

pots
pans
utensils
plates
bowls
cutting boards
sponges
towels

Labeling is your friend here.

Step 3: Clean Every Surface Thoroughly

Cleaning removes any residue, absorbed flavors, or particles that could be non-kosher.

Clean:

counters
stovetop
inside cabinets
backsplash
fridge
microwave
sink(s)

Step 4: Wait 24 Hours

Anything you are going to kosher (sinks, counters, oven, etc.) should not have hot food used on them for at least 24 hours.
This step makes the koshering process halachically valid.

PART 2 — Methods of Koshering

Judaism teaches “k’bol’o kach polto” — “the way something absorbs, that’s the way it releases.”

Meaning:

If something absorbed non-kosher flavor through heat, it’s koshered through heat.
If something absorbed through boiling, you kosher it through boiling.
If it absorbed through direct fire, you kosher it through fire.

Here’s how that works for different appliances and surfaces.

PART 3 — Koshering Appliances & Surfaces

Stovetop (Gas or Electric)

Grates

Clean thoroughly.
Let them sit unused for 24 hours.
Then put them back on the stove and turn burners to the highest flame for about 15 minutes.

Burner Area / Surface

Clean very well.
Turn each burner on high to burn off any remaining food.

Electric Coils

Turn on high until they become red-hot.

Glass Stovetops

These need:

thorough cleaning
then running at highest heat for a few minutes
You can’t pour boiling water on them (it may crack).

Oven

Standard Oven

Clean with oven cleaner until there is NO residue.
Wait 24 hours.
Turn oven to the highest temperature (usually 500ºF–550ºF) for 1–2 hours.

Self-Cleaning Oven

Self-clean cycle kosherizes it completely, because it heats extremely high.

Oven Racks

Ideally heated inside the oven during the koshering burn cycle.

Microwave

Clean it very well.
Fill a microwave-safe bowl with water.
Heat until it steams heavily (about 10 minutes).
Wipe it down.

If it has a glass turntable:

Replace if possible.
OR
Cover food being heated at all times.

Sinks

Stainless Steel Sink

Clean thoroughly.
Do not use for 24 hours.
Pour boiling water directly over every part (sink walls, base, faucet).

Porcelain Sink

Porcelain cannot be koshered with boiling water.
Options:

use sink inserts/basins (meat and dairy ones),
OR cover the sink bottom before washing dishes.

Countertops

Depends on the material.

Stainless Steel, Stone, Granite, Quartz

Clean well
Wait 24 hours
Pour boiling water over the entire surface, slowly and evenly

Laminate, Wood, or Composite

If the material can be damaged by boiling water:

Clean
Wait 24 hours
Then cover with a protective covering (vinyl, contact paper, boards)

Dishwasher

Dishwashers differ by model and interior material.

Stainless Steel Interior

Clean filter & inside well.
Wait 24 hours unused.
Run on hottest cycle with no dishes.

Plastic Interior

Different opinions exist — many rabbis advise NOT koshering it.
Some allow:

cleaning
waiting 24 hours
running on hottest cycle twice

PART 4 — Dishes, Pots, Pans, & Utensils

Can be koshered:

metal (stainless steel)
some stones
some plastics (if they withstand heat)

These are koshered with hagalah (boiling water):

Clean item thoroughly.
Do not use for 24 hours.
Dip into a large pot of boiling water.
Rinse with cold water.

Cannot be koshered:

non-stick cookware
cast iron with seasoning
ceramic
earthenware
china
Teflon

These must be replaced with kosher sets.

PART 5 — Setting Up Your New Kosher Kitchen

Here’s where your kitchen becomes beautifully organized!

✔️ Two dish racks

✔️ Two sponges

✔️ Two sinks or sink inserts

✔️ Two silverware drawers or organizers

✔️ Two cutting boards

✔️ Separate storage areas for meat and dairy

Label anything that might cause confusion.

PART 6 — Tips for Staying Kosher Long-Term

Color-coding is a lifesaver

Red for meat, blue for dairy, neutral for pareve.

Keep one section of your counter meat and another dairy

Or use mats to designate spaces.

Keep fridge shelves labeled

Helps avoid mix-ups.

Sink inserts prevent mistakes

Especially with porcelain sinks.

When in doubt — label it!
