Anyone who has packed a bear canister knows the struggle: the thing fills up fast, and dense, bulky food is the enemy. A new recipe from Backpacker tackles that problem head-on with a basil walnut ziti that comes in at just 6 oz (167 g) per serving and squeezes flat into a canister alongside the rest of a full seven-day meal plan.

The dish is essentially a deconstructed pesto pasta. At home, you precook and dehydrate a cup of ziti, then bag it with dried basil, garlic powder, chopped walnuts, and a quarter-cup of grated cashew cheese for a dairy-free, plant-based option. Olive oil travels separately in a leakproof container — double-bagged, as anyone who has had oil escape in a pack will appreciate. Total home prep is about three minutes.

In camp, it's a five-minute job if you're boiling water. Add 8 oz (240 mL) of hot water to the pasta, let it rehydrate for five minutes, drain the water responsibly per Leave No Trace principles (cold-soaking works too, but takes 45 minutes), then stir in the seasoning bag and both tablespoons of olive oil. The recipe is firm on that last point: cut the oil and you lose the pesto-style richness and end up with a drier, less satisfying meal.

The numbers make the case for itself. Each serving delivers 894 calories — 149 calories per ounce — plus 24 g of protein, 74 g of carbs, and 11 g of fiber, with zero cholesterol and a modest 324 mg of sodium, which is low by trail-meal standards. That calorie-to-weight ratio is exactly what long-distance hikers chase, since carrying a week of food means every ounce has to earn its place.

There's flexibility built in too. Swap the ziti for precooked, dehydrated chickpea pasta to make it gluten-free, or use grated parmesan instead of cashew cheese if dairy is on the menu. Because everything rehydrates in the bag, cleanup amounts to draining the water and eating — a genuine advantage when camp kitchen fatigue sets in on day four.

Why should a traveller care? Whether you're planning a week in bear country — think Sierra Nevada, Glacier, or the Adirondacks — or just want lightweight dinners for a multi-day trek, bulky food packaging is a real constraint. A complete dinner that weighs barely 150 g, needs only water, and packs enough calories for a big day of hiking solves the two biggest backcountry cooking problems at once: weight and volume. It's also cheap to make at home compared with commercial freeze-dried meals, and you control the sodium and ingredients. Even if you never carry a bear canister, the dehydrated-pasta-plus-seasoning-bag formula is a template worth stealing for any lightweight hiking menu.
