Homemade Hiking Meals: How to Dehydrate Your Own

Homemade hiking meals made in a dehydrator let you eat your own cooking on the trail: chilli, curry, pasta sauce, risotto. They're often cheaper than commercial meals, and you control the ingredients. The basic process is to cook a low-fat meal, spread it thinly, dry it until no moisture remains, and store it sealed. On the trail you add boiling water, wait, and eat.

This guide covers what dries well, how to dry it safely, rehydration ratios, storage, and three meal templates you can adapt. If you'd rather not dehydrate, see easy backpacking recipes, which uses only shop-bought dry ingredients.

Why make your own?

What dehydrates well

The key principle: dry the lean parts at home, add the fat on the trail. An olive oil sachet in the finished meal gives you back the calories without shortening shelf life.

Equipment

• A food dehydrator with trays, plus solid sheets or baking paper for sauces
• A kitchen scale
• Zip bags or vacuum-seal bags
• A permanent marker for labels

Step by step

1. Cook with less fat

Make the meal as normal, but use minimal oil and lean ingredients. Drain or blot away fat from mince.

2. Cut and spread thin

Chop pieces small (pea-sized or smaller) and spread the food in a thin, even layer, about 5 mm for sauces. Thin layers dry faster and more evenly.

3. Dry

Follow your dehydrator's manual for temperatures. Many recommend around 57 to 63 °C (135 to 145 °F) for vegetables and fruit, and higher for meat. Drying often takes 6 to 12 hours depending on the food, thickness and machine. Rotate trays partway through if drying is uneven.

4. Check it's done

• Vegetables should be brittle or crisp.
• Sauces should be leathery to brittle, peeling off the sheet cleanly with no tacky spots.
• Meat should be hard and dry all the way through.
• Break a thick piece and check the centre. There should be no moisture.

5. Cool, condition and store

Let food cool completely, then seal it in bags. Some people "condition" dried food by storing it in a jar for a few days and shaking it daily. If condensation appears, it needs more drying.

Food safety

Home dehydrating is safe when done properly, but meat needs extra care:

• Meat and poultry: USDA food safety guidance for jerky advises heating meat to a safe internal temperature (160 °F / 71 °C for beef, 165 °F / 74 °C for poultry) before drying, or as part of the process. Cooking mince fully before drying it for meals covers this.
• Use clean equipment and wash your hands.
• Store dried food cool and dry. Moisture leads to mould.
• When in doubt, throw it out. Discard anything with an off smell or visible mould.

Follow guidance from your national food safety authority or a cooperative extension service. They publish detailed home-drying instructions.

Rehydration ratios

Weigh each meal dry, and write the water amount on the bag. As a starting point:

These vary a lot with the recipe, so test each meal at home. Freezer-bag cooking, where you pour boiling water into the bag and wrap it in a cosy, works well with homemade meals.

Three meal templates

Template 1: Trail chilli

Template 2: Bolognese pasta

Template 3: Red lentil dal with rice (vegan)

Each template lands roughly in the 600 to 800 kcal range once the trail add-ons are included, depending on your ingredients. Check yours with the calorie density checker, or total a recipe's protein with the meal prep recipe scaler.

Oven drying as an alternative

If you don't own a dehydrator, an oven can work for small batches, although it's less efficient and harder to control. Typical approaches used by home cooks:

1. Set the oven to its lowest temperature. Many ovens don't go below 50 to 70 °C, which is warmer than a dehydrator's vegetable setting.
2. Line trays with baking paper and spread the food thinly.
3. Prop the door open slightly with a wooden spoon so moisture can escape.
4. Check often, because food at the edges dries faster.
5. Expect it to take many hours, and be careful about leaving an oven on unattended.

Results are often less even than in a dehydrator. A small, inexpensive dehydrator is usually worth it if you plan to dry more than a few meals a year.

Making meals denser

Dried home meals are often lower in calories than you might expect, because most of the fat has been removed. On the trail, add fat back with olive oil, butter powder, coconut oil, grated hard cheese or nuts. One 15 ml oil sachet adds about 120 kcal. Two sachets in a dinner can bring a lean homemade chilli up to a satisfying size for a long day.

Batch-making for a trip

1. Cook a big batch of two or three base meals.
2. Dry them over a weekend.
3. Weigh and portion them into single-meal bags.
4. Add shop-bought dry parts such as rice, pasta and potato flakes.
5. Label each bag with the name, water amount and trail add-ons.
6. Plan the trip with the trail meal planner.

Storage and shelf life

Homemade meals generally don't last as long as commercial freeze-dried food. Practical guidance from home dehydrators:

• Store sealed, cool, dark and dry.
• Use low-fat meals within a few months; freeze them for longer.
• Meals containing meat are best used sooner or kept frozen until the trip.
• Vacuum sealing and oxygen absorbers can extend shelf life.

Common mistakes

1. Too much fat in the base meal, which dries poorly and can go rancid.
2. Pieces too big, which dry and rehydrate unevenly.
3. Not drying long enough, leaving moisture in the centre.
4. Untested water amounts, giving soupy or crunchy dinners.
5. Forgetting the fat on the trail, leaving meals low in calories.

Checklist

• ☐ Low-fat base meals cooked
• ☐ Meat cooked to a safe temperature before drying
• ☐ Spread thin, dried until no moisture remains
• ☐ Cooled, conditioned and sealed
• ☐ Bags labelled with water amount and add-ons
• ☐ Each meal tested at home
• ☐ Oil and cheese packed for the trail
