- 2 Tablespoons Butter: This rich fat is essential for adding flavor and helping the onions cook down smoothly. For a dairy-free option, feel free to use coconut oil or vegan butter.
- 1 teaspoon All Purpose Seasoning Blend: This seasoning enhances the natural sweetness of the onions. If you don’t have it on hand, a pinch of salt and pepper works wonders too!

How to Make Instant Pot Caramelized Onions
Combine Ingredients: Begin by adding the 2 pounds of sliced white onions, 2 tablespoons of butter, and 1 teaspoon of all-purpose seasoning blend to your Instant Pot. Toss everything together to ensure the onions are well-coated.
Cook Under Pressure: Secure the lid on the Instant Pot and adjust the vent to seal. Set it to cook on high pressure for 5 minutes. During this time, the onions will soften and release their moisture, laying the groundwork for that rich flavor.
Release Pressure: Once the cooking time is up, do an immediate pressure release to avoid overcooking. Carefully remove the lid, exposing the perfectly softened onions.
Drain Excess Liquid: Use a slotted spoon or strain the onions to eliminate any excess liquid. This step is crucial for getting that nice caramelized texture later on.
Sauté the Onions: Return the drained onions to the pot, and switch on the sauté setting. Stir in one tablespoon of brown sugar, mixing it well with the onions. Sauté for another 3-5 minutes, until they turn golden brown and fragrant, stirring occasionally to prevent sticking.
Serve Immediately: Once the onions are beautifully caramelized, they’re ready to be enjoyed! Use them to enhance your favorite dishes or simply savor them by the spoonful.
Storing & Reheating
To store your Instant Pot Caramelized Onions, let them cool completely before transferring to an airtight container, where they’ll last up to a week in the refrigerator. For long-term storage, freeze the onions in a freezer-safe container or zip-top bag for up to 3 months. When you’re ready to enjoy them again, just reheat them gently in the microwave or in a skillet on the stovetop, adding a splash of water if necessary to refresh the texture.
Chef’s Helpful Tips
- Always slice the onions uniformly to ensure even cooking. A sharp knife helps make this process much smoother.
- Keep an eye on the sauté process—too high of a heat can burn the sugar, leading to an unpleasant bitter taste. If they start to stick, add a little butter or water.
- Feel free to experiment by adding herbs like thyme or rosemary while the onions sauté for a fragrant touch.
- Want them sweeter? Stir in an additional teaspoon of brown sugar during the sauté phase.
- These caramelized onions can easily be made ahead of time. Just warm them up before serving!
Rich and versatile, Instant Pot Caramelized Onions are a must-try dish that enriches a variety of meals. They’re an instant upgrade to anything you add them to, introducing a gourmet touch with minimal effort.
