1. Solar Ovens

Solar ovens use sunlight to trap heat, functioning like a small greenhouse. They’re great for slow cooking, baking, and reheating. If you have reliable sun, solar ovens are simple and extremely low cost to operate.

How solar ovens work

Solar ovens concentrate sunlight with reflective panels or a clear lid. Sunlight enters and is absorbed by the dark interior and cookware, converting to heat. Insulation reduces heat loss, allowing internal temperatures to reach 250–400°F (120–205°C) depending on design and sun strength.

You’ll see two common types: box ovens (insulated with glass or plastic lids) and panel ovens (folding reflectors). Panel ovens are lightweight and portable; box ovens hold higher and more stable temperatures.

What you can cook

You can bake breads, roast meats at low temperature, simmer soups, and reheat foods. Foods that benefit from slow, steady heat — beans, casseroles, stews, rice, and baked goods — perform best. Fast searing or high‑temperature frying is not practical.

Suggested uses:

Slow‑roasted chicken or vegetables
Casseroles and baked pasta
Breads and muffins
Slow‑cooked beans

Setting up and using a solar oven

Position the oven facing the sun; angle the reflectors for maximum direct sunlight.
Preheat for 15–30 minutes if possible.
Use dark, lidded cookware to absorb heat efficiently.
Monitor temperature with a simple oven thermometer; adjust reflectors every 20–30 minutes as the sun moves.
Use an insulated pad to reduce heat loss from the bottom if surface is cool.

Pros and cons

Pros:

No fuel cost and minimal maintenance
Safe and clean — no combustion
Excellent for long, unattended cooking

Cons:

Dependent on clear skies and daylight
Slower cooking times
Limited high‑heat capability

Practical tips

Use cookware with tight lids to retain moisture.
Plan meals for sunny days; have a backup method for cloudy weather.
Build or buy a solar oven with good insulation and robust reflectors.
Keep a thermometer to judge performance.

Example recipe: Solar oven chili

Brown onions and garlic on a small portable stove or use precooked browned meat.
Combine beans, diced tomatoes, spices, meat, and a small amount of broth in a dark pot with lid.
Place in solar oven for 4–6 hours at 250–300°F, stirring once or twice.
Adjust seasoning before serving.

2. Rocket Stoves

Rocket stoves are compact combustion systems designed for efficient, high‑temperature burning of small sticks and biomass. You’ll find them excellent for quick boiling, frying, and other high‑heat tasks.

How rocket stoves work

Rocket stoves rely on a vertical insulated combustion chamber and a horizontal feed tube. The insulation keeps the fire hot, producing more complete combustion with less smoke. The design directs heat to a small pot surface, maximizing fuel efficiency.

What you can cook

Rocket stoves reach boiling temperatures quickly and are suitable for frying, sautéing, searing, boiling water, and most pot‑based cooking. They’re not ideal for baking without additional accessories.

Common uses:

Boiling water for purification or cooking
Stir‑fries, pancakes, eggs, and quick sautés
One‑pot meals and soups

Fuel and fuel preparation

Use small, dry sticks, twigs, and other biomass. Little or no splitting is required if sticks are the right size. For longer burn times, use a combination of small kindling to start, adding slightly larger sticks as the fire stabilizes.

Fuel tips:

Use dry wood for fast ignition and low smoke.
Avoid green wood and damp leaves — they produce smoke and reduce heat.
Bundle fine twigs as emergency tinder.

Building or buying a rocket stove

You can buy compact metal rocket stoves or build one from a tin can, bricks, or rocket stove kits. When building, use insulating material like perlite or clay in the combustion chamber for efficiency.

Operation steps

Place the stove on a stable, heat‑resistant surface.
Feed small dry sticks into the fuel intake and light the tinder.
Once the combustion chamber is hot, add larger sticks gradually.
Position your pot directly over the heat collar for efficient transfer.
Adjust fuel feed to control heat.

Safety

Keep the stove away from flammable materials and overhead obstructions.
Use pot holders — metal parts get hot.
Extinguish remaining embers after cooking, and store ashes safely.

Pros and cons

Pros:

Extremely fuel efficient
Quick to reach cooking temperatures
Portable models available

Cons:

Requires dry biomass
Limited cooking area for large pots or multiple pans
Some initial learning for optimal fuel feed

Example recipe: One‑pot rice and vegetables

Sauté chopped onions and carrots in a small splash of oil until softened.
Add rice, water (1:2 rice to water), and diced tomatoes or seasoning.
Bring to a boil, reduce heat by controlling fuel, and simmer 15–20 minutes until water is absorbed.
Stir and serve.

3. Wood‑Burning Stoves (Indoor/Outdoor) — Potbelly, Woodstove, and Rocket‑Bolt Stoves

Wood‑burning stoves offer a central heat source and a steady cooking surface, suitable for cabin life or long‑term off‑grid households. They can heat your living space and provide reliable cooking options.

How wood‑burning stoves function

A wood stove burns logs inside a firebox. Heat is radiated from the stove body and transferred to pots on top. Some models include ovens or flat cooktops. Proper installation requires a chimney or flue for smoke ventilation.

Types and features

Potbelly stoves: Traditional durable designs, good for heat and cooking.
Modern wood stoves: Efficient, cleaner burning with air control.
Masonry stoves: Retain heat and radiate for long durations.
Combined cookstoves: Include oven compartments for baking.

Choose a model rated for cooking and matching your space constraints and heating needs.

Cooking applications

You’ll be able to simmer stews, boil, fry, and bake with proper accessories. With a woodstove, you can maintain a simmer for hours and bake using cast iron or baking sheets.

Good uses:

Long stews and braises
Baking bread using Dutch ovens or loaf pans
Cooking multiple pots at once

Installation and ventilation

Install with a properly sized chimney to ensure draft.
Use heat shields and maintain recommended clearances from combustibles.
Install carbon monoxide detectors in living spaces where you use combustion appliances.

Fuel management

Seasoned hardwood provides long, hot burns. Softwoods burn faster but are useful for quick fires. Store wood in a dry, ventilated area to maintain fuel readiness.

Pros and cons

Pros:

Provides both heat and cooking surface
Works in cloudy or winter conditions
Can cook many dishes, including baking

Cons:

Requires permanent installation and venting
Needs steady fuel supply and maintenance (ash removal, chimney cleaning)
Not as portable

Practical tips

Use cast iron cookware to use the heat evenly and retain warmth.
Keep a small kettle of water on the stove to humidify indoor air during winter.
Learn to control air inlets for simmering vs. high heat.

Example technique: Baking bread on a woodstove

Preheat the stove so the top is evenly hot.
Use a Dutch oven or loaf pan with a lid and preheat it on the stove.
Place dough in the preheated vessel and set on the stove surface or inside the stove’s oven if available.
Use embers or controlled heat to maintain about 375°F until baked.

4. Dutch Oven Cooking Over Coals

A cast iron Dutch oven combined with coals or embers provides versatile, reliable cooking for baking, roasting, simmering, and frying. You’ll use coals both under and on top of the oven lid to create even heat similar to an oven.

How it works

Cast iron holds and distributes heat evenly. By arranging hot coals under the pot and on the lid, you create a two‑sided heat source that bakes and roasts much like an oven. This method is popular for outdoor gatherings and long‑camp cooking.

Fuel sources

You can use charcoal briquettes, lump charcoal, or wood embers. Charcoal offers predictable temperature control, while wood embers are available if you have a campfire.

Temperature guidelines (approximate by number of coals):

Low (250–300°F): 8–12 coals (for a 10–12″ Dutch oven)
Moderate (300–350°F): 12–18 coals
High (350–425°F): 18–24 coals

Exact numbers depend on oven size and ambient conditions.

Cooking types

Bread and cakes: Use top and bottom coals for even baking.
Roasts and stews: Simmer with fewer coals for long braises.
Frying and sautéing: Use fewer coals under the pot and control airflow.

Steps to cook with a Dutch oven over coals

Prepare coals: light charcoal or build a wood fire and collect embers.
Preheat the Dutch oven by placing it over a few coals for 5–10 minutes.
Add food and replace the lid.
Place the appropriate number of coals under and atop the lid.
Rotate lid and pot every 10–15 minutes for even cooking.
Use mitts and tongs to handle hot coals and cookware.

Pros and cons

Pros:

Versatile: bakes, roasts, stews, fry
Relatively simple and robust equipment
Works in many weather conditions

Cons:

Requires coal or ember management
Heavy cookware (cast iron)
Can be messy with ash

Practical tips

Use a coal rake and tongs for safe handling.
Clean and season cast iron after use to prevent rust.
Keep a shallow pan of water for quick extinguishing of stray coals.

Example recipe: Dutch oven cobbler

Add fruit, sugar, and a bit of lemon juice to the preheated oven.
Spoon biscuit or batter topping over fruit.
Place 10–12 coals underneath and 12–16 on the lid for a 10″ oven.
Bake 25–40 minutes until golden.

5. Alcohol and Solid Fuel Stoves (Denatured Alcohol, Hexamine Tabs)

Alcohol and solid fuel stoves are popular for lightweight camping and as emergency backups. They are compact, quiet, and simple to operate, making them reliable in many off‑grid situations — though they have limited power and run time.

Types and fuel

Alcohol stoves: Use denatured alcohol or methylated spirits. They’re lightweight and can be homemade or purchased.
Solid fuel stoves: Use hexamine tabs (Esbit) or similar solid fuels. Tabs are stable, lightweight, and store well.
Esbit and similar stoves are compact and have integrated windshields in some designs.

What you can cook

These stoves are excellent for boiling water, making hot drinks, reheating packaged meals, and simple one‑pot cooking. They’re less suitable for extended frying or multiple pans.

Operation and safety

Place stove on a stable, wind‑protected surface.
Pour an appropriate amount of fuel into an alcohol stove; light carefully.
Use a windscreen to maintain flame and reduce cooking time.
Never move a lit stove; extinguish or let fuel burn out before handling.
For tabs, ignite the tab and position your pot on the provided pot supports.
Pour a small amount of water over hot ashes to extinguish in emergencies; follow fuel manufacturer guidance.

Pros and cons

Pros:

Lightweight and easy to transport
Quiet and low maintenance
Fuel stores compactly

Cons:

Lower heat output and shorter run times
Fuel may be flammable and needs safe storage
Tabs may leave residues or stink

Practical tips

Carry spare fuel and a small bottle or canister for alcohol.
Use a proper fuel bottle designed for denatured alcohol to reduce leaks.
Keep a lighter or matches specifically stored with the stove.

Example: Quick pasta on an alcohol stove

Bring a pot of salted water to a rolling boil.
Add pasta and cook according to package directions.
Use a lid to speed boiling and conserve fuel.
