Exploring the Science: Why Does Pasta Take Longer to Cook in the Mountains?

Why Does Pasta Take Longer to Cook in the Mountains?

Pasta, the quick and easy meal packed with energy, is a favorite among hikers, backpackers, and climbers in the mountains. But have you ever wondered why it takes longer to cook pasta in mountainous regions? In this article, we’ll delve into the science behind this phenomenon and provide you with some tips to make cooking pasta in the mountains a breeze, so you can spend more time enjoying your outdoor adventure.

The Science Behind It

At higher elevations, water boils at a lower temperature than at sea level. Although the water is indeed boiling, it is several degrees cooler than the standard 212 degrees Fahrenheit (100 degrees Celsius) that we usually consider as the boiling point. As a result, the boiling pasta water is cooler than expected, making the pasta take longer to cook.

To achieve perfectly cooked pasta in the mountains, it’s essential to understand this science and adjust cooking times accordingly. Keep in mind that there isn’t a one-size-fits-all solution, so read on to discover how to make a delicious pasta dish in the mountains or anywhere else.

Cooking Pasta at High Altitudes

Regardless of whether you’re cooking in a modern kitchen, on a camp stove, or over a fire, the basic method for cooking pasta remains the same: boiling it in lightly salted water until it reaches the desired texture. Typically, we refer to the directions on the box to determine the cooking time, which is a good starting point.

However, when you’re cooking at high altitudes, such as when camping or hiking in the mountains, adjustments need to be made to achieve perfectly cooked pasta. Wasting food isn’t ideal, especially when you’re backpacking in a remote area without easy access to replacement ingredients.

The Impacts of High Altitude and Air Pressure

At higher elevations, the air pressure is lower. For the purpose of this article, let’s consider “high altitude” to be above 3,000 feet. Compared to sea level, the atmospheric pressure decreases significantly. This decrease in air pressure affects the boiling point of water.

For every 500 feet above sea level, the boiling point of water is reduced by slightly less than one degree Fahrenheit. At approximately 7,500 feet above sea level, the boiling point of water drops to 198 degrees Fahrenheit. Consequently, the boiling water in the mountains is cooler than the standard 212 degrees Fahrenheit, leading to longer cooking times for pasta.

Mastering the Art of Cooking Pasta in the Mountains

To cook pasta efficiently in high-altitude environments, follow these DOs and DON’Ts:


  • Choose the right pasta for the sauce: Delicate oil-based sauces pair well with long, thin noodles, while heavy sauces adhere better to tube or twisted pasta.
  • Cook the right amount of pasta: A standard serving is about two ounces per person, and pasta roughly doubles in size when cooked.
  • Wait for the water to reach a full, rolling boil: Adding pasta to boiling water that isn’t at its peak will result in sticky and gummy noodles.
  • Stir at regular intervals: This prevents the pasta from clumping and ensures even cooking.
  • Save a cup of pasta water: It’s useful for adjusting the thickness of the sauce when dressing the pasta.
  • Add pasta to the sauce: Allowing the pasta to “finish” in the hot sauce lets it absorb the flavors more effectively.
  • Transfer pasta with a spider: Using a wide wire skimmer, transfer the pasta from the pot to the sauce. It’s less messy and safer than carrying a pot of boiling water to the sink.

  • Add oil to the pasta water: It won’t prevent the noodles from sticking together but will hinder the sauce from sticking to the pasta. If not serving immediately, toss the drained pasta with olive oil.
  • Rinse the pasta: Rinsing removes starch, compromising flavor and texture.
  • Rely solely on cooking times on the box: Instead, test the pasta’s texture as it cooks. Most prefer al dente pasta, which should be firm and slightly resistant. Remove the pasta from the heat and drain it when it’s just short of perfection, as it continues to cook in the pan.

Frequently Asked Questions

Can you pre-cook pasta for backpacking?

Yes, you can pre-cook pasta for backpacking. Simply boil the pasta ahead of time, store it in tightly sealed Ziploc bags, and it will remain good for up to 48 hours when kept in a cool, dry place. You can reheat the noodles with sauce or enjoy them cold. However, keep in mind that pre-cooked pasta is heavier than dry pasta, so consider weight-saving options.

How do you cook pasta on the trail?

Many hikers prefer the “pre-soak” method for cooking pasta on the trail. Soak the pasta in a bowl of room temperature water for 60-90 minutes or until the noodles float. Then, drain the water and seal the pasta for storage in your pack. When you crave a spaghetti dinner, it will take only 1-2 minutes of boiling to reach al dente tenderness.

How do you cook pasta on a camping stove?

Boiling a large pot of water on a camping stove can be time-consuming and cumbersome. Try using your large mug instead. Break the pasta noodles into small pieces, fill the mug with water, and bring it to a rapid boil. Cover the mug with a lid or foil, allowing the noodles to steam and simmer in the residual heat. This method saves time and fuel.

Is pasta good for backpacking?

Pasta is a common food staple among backpackers, thanks to its affordability and high carbohydrate content. However, it can be challenging to cook on the trail and may become monotonous after a few nights. Despite these drawbacks, pasta remains a popular choice for its energy-rich properties.

What do you do with pasta water when camping?

Pasta water, rich in starch, serves as an excellent base for delicious sauces. Additionally, it’s perfectly acceptable to drink or reuse for 1-2 more batches of pasta or rice.

What is the quickest cooking pasta?

Thin or small pasta varieties cook quickly. Angel hair and orzo pasta, for example, can be cooked al dente in about 5 minutes. They mix well with soups or sauces when you’re on the trail.
