Ingredients

• 4 medium yellow onions (about 1.5 lbs or 680 g), peeled and quartered
• ¼ cup (60 ml) extra virgin olive oil
• ½ teaspoon (2.5 g) sea salt
• ¼ teaspoon (0.5 g) black pepper, freshly ground

Ingredient Notes

• Onions: Yellow or white onions work best for their balanced flavor. Red onions can be used for a slightly sharper, more pungent paste. Ensure they are peeled and roughly quartered for easy blending.
• Olive Oil: Extra virgin olive oil adds a lovely fruity note and helps create a smooth paste. You can use any neutral-flavored oil like avocado or grapeseed oil if preferred, but olive oil contributes significantly to the flavor.
• Salt and Pepper: These are essential for seasoning the paste from the start, enhancing the natural flavors of the onion. Adjust quantities to your taste or dietary needs.

Equipment You’ll Need

• High-speed blender or food processor
• Measuring cups and spoons
• Rubber spatula
• Airtight storage container or ice cube trays

How to Make Easy Blended Onion Paste

1. Prepare the Onions: Begin by peeling the 4 medium yellow onions. Once peeled, roughly quarter each onion. This makes them easier for your blender or food processor to handle.
2. Add to Blender: Place the quartered onions into the pitcher of your high-speed blender or the bowl of your food processor.
3. Add Seasoning and Oil: Pour the ¼ cup (60 ml) of extra virgin olive oil over the onions. Sprinkle in the ½ teaspoon of sea salt and ¼ teaspoon of freshly ground black pepper.
4. Blend Until Smooth: Secure the lid on your blender or food processor. Start blending on a low speed, gradually increasing to high. Blend until the onions are completely broken down into a smooth, consistent paste. This may take 1-2 minutes, depending on your appliance. You might need to pause and scrape down the sides with a rubber spatula to ensure everything is incorporated.
5. Check Consistency: The paste should be smooth with no large chunks of onion remaining. It should have a slightly thick, pourable consistency.
6. Transfer and Store: Carefully transfer the blended onion paste to an airtight container. It’s now ready to be used or stored for future meals.

Pro Tips for the Best Results

• Cut Onions Evenly: Quartering the onions into roughly equal sizes helps them blend more uniformly and prevents larger pieces from escaping the blades.
• Don’t Overfill the Blender: If you have a smaller blender, blend the onions in two batches to ensure a smooth consistency without overworking your appliance.
• Scrape Down the Sides: Periodically stop your blender or food processor and scrape down the sides with a spatula. This ensures all onion pieces are drawn into the blades for a perfectly smooth paste.
• Adjust Oil as Needed: While ¼ cup is typically sufficient, you can add another tablespoon or two of olive oil if your onions are particularly dry or if you prefer a thinner paste.
• Taste and Adjust Seasoning: Before storing, taste a tiny bit of the paste (raw onion flavor will be strong, but you can assess salt and pepper levels). Adjust salt and pepper as desired.
• Use Fresh Onions: The fresher your onions, the better the flavor of your paste. Avoid onions with soft spots or sprouts.

Common Mistakes to Avoid

• Not Peeling Onions Thoroughly: Any papery skin left on the onions can result in an unpleasant texture in the final paste.
• Under-Blending: Leaving large chunks of onion will compromise the smooth texture and even distribution of flavor in your cooking. Blend until completely smooth.
• Overheating the Blender: If blending a large batch, give your blender short breaks to prevent it from overheating.
• Using Too Little Liquid: Without enough olive oil, the onions might struggle to blend into a smooth paste, leading to a chunky or uneven consistency.
• Forgetting to Season: While you’ll season your final dish, pre-seasoning the paste helps to develop the onion’s flavor and ensures a balanced taste from the start.

Variations & Substitutions

• Garlic & Ginger Infusion: Add 2-3 cloves of peeled garlic and a 1-inch piece of peeled fresh ginger along with the onions for an aromatic South Asian or Asian-inspired flavor base.
• Spicy Kick: Include a deseeded jalapeño or serrano pepper for a subtle heat, or a pinch of red pepper flakes.
• Herbal Twist: For certain dishes, you could add a small handful of fresh cilantro or parsley during the last few seconds of blending.
• Sweet & Savory: A tiny splash of balsamic vinegar or a pinch of sugar can enhance the sweetness of the onions, perfect for caramelized onion bases.
• Oil Type: While olive oil is recommended, coconut oil (for Asian flavors), or a neutral oil like avocado or grapeseed oil can also be used.

Serving Suggestions

This blended onion paste is a versatile building block for countless meals. Here are some ideas:

• Curries and Stews: Sauté a few spoonfuls of the paste before adding your spices and other ingredients to build a rich, aromatic base.
• Soups and Sauces: Incorporate into the beginning of your soup or pasta sauce recipes for a deeper, more cohesive flavor.
• Marinades: Add a tablespoon or two to meat, poultry, or vegetable marinades for an extra layer of savory flavor.
• Ground Meat Dishes: Mix into ground beef, turkey, or chicken for meatballs, meatloaf, or taco filling to keep them moist and flavorful.
• Stir-Fries: Quickly sauté with other vegetables and proteins for a fast, flavorful stir-fry base.
• Dressings and Dips: A small amount can add complexity to homemade salad dressings or savory dips.

Storage & Reheating

• Refrigerator Storage: Store the blended onion paste in an airtight container in the refrigerator for up to 5-7 days. The oil helps preserve it.
• Freezer Suitability: This paste freezes beautifully! For easy portioning, spoon it into ice cube trays. Once frozen solid (after about 4-6 hours), transfer the frozen cubes to a freezer-safe bag or container.
• Approximate Storage Duration (Freezer): Blended onion paste can be stored in the freezer for up to 3 months without significant loss of flavor.
• Reheating Method: When ready to use, simply drop a frozen cube or spoon a desired amount directly into a hot pan with a little oil. It will thaw and cook down quickly. There’s no need to thaw it beforehand.
• Maintaining Texture: Freezing and thawing will not significantly alter the texture or flavor profile when used in cooking.
