Yams are a delicious, versatile ingredient that can be used in a variety of dishes, from savory casseroles to sweet desserts. If you’re looking to prepare yams quickly while retaining their rich flavor and nutritional benefits, pressure cooking is your best bet. This method dramatically reduces cooking time while preserving the natural sweetness and texture of the yams. In this article, we will delve into how long to pressure cook yams, the benefits of pressure cooking, and tips for ensuring your yams come out perfect every time.
Understanding Yams: What You Need to Know
Before diving into pressure cooking, it’s important to understand what yams are and how they differ from sweet potatoes.
The Difference Between Yams and Sweet Potatoes
Often confused with sweet potatoes, yams belong to the Dioscorea family, while sweet potatoes belong to the Convolvulaceae family. Here are a few distinctions:
- Origin: Yams are native to Africa, Asia, and the Caribbean, while sweet potatoes are largely grown in the United States and other warm climates.
- Texture: Yams tend to have a starchy texture and a dry flesh, while sweet potatoes are sweeter and creamier.
Knowing this difference helps in choosing the right ingredient for your dish.
Benefits of Pressure Cooking Yams
Pressure cooking yams comes with several advantages that make it a preferred method for many home cooks:
1. Time-Saving
One of the most significant benefits of pressure cooking is the reduction in cooking time. Traditional methods like boiling or baking can take up to an hour or more. In contrast, pressure cooking yams typically takes only 15 to 30 minutes, depending on their size.
2. Nutrient Preservation
When yams are cooked under pressure, they retain more nutrients compared to traditional boiling, which can leach vitamins and minerals into the water. Pressure cooking locks in flavors and nutrients, allowing you to enjoy healthier meals.
3. Enhanced Flavor
Cooking yams under pressure intensifies their natural sweetness and helps to enhance their flavor, making them a treasured part of any dish.
How Long to Pressure Cook Yams
The cooking time for yams in a pressure cooker can vary based on a few factors, including the size of the yams and whether they are whole or cut. Here’s a breakdown of the recommended cooking times.
Whole Yams
- Small yams (1-2 inches/2.5-5 cm): Pressure cook for about 15-20 minutes.
- Medium yams (2-3 inches/5-7.5 cm): Aim for about 20-25 minutes.
- Large yams (3-4 inches/7.5-10 cm): Cook for about 25-30 minutes.
Cut Yams
If you prefer to cut your yams into chunks, cooking time can be significantly reduced:

Check for Doneness
- Test the Yams: Insert a fork or knife into the yams. They should be tender and easily pierced. If not, you can seal the cooker again and cook for an additional few minutes.
Serving Suggestions for Pressure-Cooked Yams
Once your yams are perfectly cooked, the possibilities for serving are endless. Here are a few serving suggestions to enhance their rich flavor:
1. Mashed Yams
Mash the pressure-cooked yams with a bit of butter, salt, and pepper for a rich and creamy side dish. You can also add spices like cinnamon or nutmeg for a sweeter flavor.
2. Roasted Yams
For a roasted flavor, toss cooked yams with olive oil and herbs, then place them in the oven to crisp up for about 15-20 minutes.
3. Yams in Stews and Casseroles
Chunk up your cooked yams and add them to stews or casseroles for an extra dimension of flavor and nutrition.
4. Sweet Potato Pie
If you’re feeling adventurous, use your cooked yams as a base for a delicious sweet potato or yam pie, offering a unique twist on traditional recipes.
Tips for Cooking Yams in a Pressure Cooker
To ensure your yams turn out perfect every time, consider these handy tips:

Whether you are using them in a savory dish, creamy mash, or sweet dessert, pressure-cooked yams will elevate your meal and impress your guests. Happy cooking!
What are yams, and how do they differ from sweet potatoes?
Yams are starchy tubers that belong to the Dioscorea genus, originating from Africa and Asia. They have a rough, scaly skin and a creamy white, purple, or pink flesh. Yams are often confused with sweet potatoes, but they are distinct species, with sweet potatoes being sweeter, softer, and more commonly found in grocery stores in the U.S.
Sweet potatoes belong to the Convolvulaceae family and have a smooth skin with orange, white, or purple flesh. The most notable difference lies in their taste and texture; yams tend to be starchier and drier, while sweet potatoes are creamier and the sweetness varies with type. Both are nutritious but offer different culinary uses.
How long do you need to pressure cook yams?
To achieve perfectly cooked yams in a pressure cooker, the typical time ranges from 15 to 20 minutes, depending on the size of the yam pieces. If you are cooking whole yams, it can take about 25 to 30 minutes. It is essential to cut them into evenly sized pieces to ensure that they cook uniformly.
Additionally, remember to allow for natural pressure release after the cooking time is completed. This guarantees the yams finish cooking gently, preserving their moisture and flavor. Always consult your pressure cooker’s manual for specific guidelines.
Should yams be peeled before pressure cooking?
You can choose to peel yams before cooking, but this is not necessary. Cooking yams with the skin on can help retain nutrients and add texture. The skin can easily be removed afterward, allowing for convenient preparation, especially if you plan to mash or puree the yams.
If you prefer your yams peeled, it’s best to do this before cutting them into smaller pieces. Peeling can be easier once they’ve been cooked if you’re looking for a hassle-free preparation method.
How can you tell when yams are done cooking?
The best way to check if yams are done cooking is to use a fork or a knife. If it easily pierces through the flesh without resistance, the yams are perfectly cooked. This tender texture indicates that they are ready to be served or further prepared according to your recipe.
If they are still firm, you can seal the pressure cooker again and cook them for an additional 3 to 5 minutes, then test again. Be cautious not to overcook, as they can become mushy if left in the pressure cooker for too long.
Can you cook yams from frozen in a pressure cooker?
Yes, you can cook frozen yams in a pressure cooker, but the cooking time will be slightly longer than when using fresh yams. For frozen yams, consider adding an additional 5 to 10 minutes to the normal cooking time. Remember to factor in the time it takes for the pressure cooker to come to pressure with the added volume of cold yams.
When cooking from frozen, it’s important to know that the texture may differ slightly. Frozen yams may release more moisture, which can impact their overall consistency once cooked. It’s best to ensure they are evenly cut to ensure they cook through properly.
What flavors pair well with yams?
Yams are versatile and can complement a variety of flavors. They pair beautifully with savory spices like cinnamon, nutmeg, and allspice, or even herbs like rosemary and thyme. These flavors enhance their natural sweetness and create delightful contrasts, making them a fantastic side dish for meats or other savory meals.
Additionally, yams are excellent with toppings or mixes that incorporate butter, brown sugar, maple syrup, or even pecans and marshmallows. These combinations can create a sweet, dessert-like dish, perfect for special occasions and holiday meals, showcasing their unique flavor profile.
Is it necessary to add water when pressure cooking yams?
Yes, adding water is essential when pressure cooking yams. The moisture produced by the water is what generates steam, allowing the pressure cooker to build pressure and cook the yams thoroughly. Typically, you will want to add at least one cup of water for effective cooking.
The amount of water can vary depending on your pressure cooker and the number of yams being prepared. Always refer to your specific pressure cooker’s instructions to determine the optimal amount of liquid to use for the best cooking results.
