Meal prep, in stainless steel.

Why is stainless steel good for meal prep?

Meal prep is repetition: the same containers filled, chilled, reheated and washed, week after week. That repetition is exactly what wears soft materials out — tomato stains that never lift, odors that carry into the next meal, surfaces that scratch and cloud in the dishwasher.

304 (18/8) stainless steel does not do any of that. It is the same material used in professional kitchens for the same reason: it shrugs off staining, takes a proper scrub without damage, and looks the same in year five as it did in week one. The Prep Series containers are SGS dishwasher-tested to EN 12875-1 over 50 cycles, and rated for the refrigerator and freezer.

• No staining or odor carry-over from sauces, spices or dressings
• Dishwasher-safe — SGS tested, EN 12875-1, 50 cycles
• Refrigerator and freezer safe — SGS tested
• Microwave-safe by design — engineered for it, SGS tested
• One uncoated food-contact surface: 100% 304 (18/8) stainless steel

Built for the gym bag and the work week

A meal-prep routine only survives if the containers keep up with it. The Prep Series 3-pack is sized for real portions — 27 oz (800 ml) holds a full meal of protein, carbs and vegetables — and the three containers stack flat in the refrigerator so Sunday's cooking becomes Monday, Tuesday and Wednesday's meals without another decision.

At the office or the gym, reheating is the honest test. Most stainless steel containers fail it — metal and microwaves famously do not mix. These were engineered for the microwave and SGS-tested for it, so lunch goes from refrigerator to hot without changing containers. At home, the container (without its lid) can also go straight into the oven.

Clean eating starts with the container

If you are careful about what goes into your food, the container it lives in is part of the same decision. The Prep Series food-contact surface is uncoated 304 (18/8) stainless steel — there is no synthetic coating to scratch, flake or wear into your meals, because there is no coating at all. Made without intentionally added PFAS, and we publish the test reports behind every claim on our Materials & Safety page.

We are honest about the limits too: the lid is rated for the refrigerator, freezer, microwave and dishwasher — not the oven. When a fact is not tested, it does not appear on this site.

What are the benefits of stainless steel?

Durability is the quiet one. Steel does not ask to be replaced: it survives the dishwasher indefinitely, takes metal utensils and hard scrubbing, and does not degrade with heat cycles the way coated or soft materials do. When a container finally does retire, stainless steel is endlessly recyclable.

That is the buy-once argument in one line: a material that performs the same on wash two hundred as it did on wash one, backed by our 5-Year Warranty.

From the skillet to the container

The routine works best as one system: batch cook in an uncoated Sear Series skillet — the browning that real searing builds is most of what makes reheated food still taste cooked, not warmed up — then portion straight into the three Prep Series containers while the pan is still warm.

One cooking session, three meals stacked in the refrigerator, and a skillet that cleans up with a scourer and no anxiety about damaging a coating.
