Ingredients for French Onion Compound Butter
Here’s what you’ll need to make this delicious French Onion Compound Butter:
1 medium onion – Choose a sweet onion for a richer flavor; yellow onions also work great for a slightly sharper taste.
2 tablespoons olive oil – Using quality olive oil enhances the flavor profile; you can also substitute with butter for a richer base.
1/4 teaspoon salt – Adjust to taste; it helps to bring out the sweetness of the onions.
1/2 teaspoon erythritol – A natural sweetener that balances the flavors; if you prefer, you can use sugar or honey.
8 ounces butter – Unsalted butter is preferable, allowing you to control the saltiness; make sure it’s softened for easy blending.
Salt to taste – Additional seasoning to suit your preferences at the end of preparation.
How to Make French Onion Compound Butter
Follow these simple steps to prepare this delicious French Onion Compound Butter:
Step 1: Sauté the Onions
Place the olive oil into a non-stick frying pan over high heat. Once the oil is hot and shimmering, add the chopped onion and sauté, stirring continually until it softens and turns lightly brown.
Step 2: Bring the Sweetness
Once the onions are soft, add the salt and erythritol. Continue cooking, stirring regularly, until the onions become browned and sticky. This process is crucial for that deep, caramel flavor, so don’t rush it! Remove the pan from heat and set aside to cool completely.
Step 3: Blend Together
Add the cooled onions to your food processor and blend on high for about 1 minute. This step releases the rich flavors trapped within those caramelized beauties, creating an enticing aroma that wafts through the kitchen.
Step 4: Mix with Butter
Now, toss in the softened butter with the blended onions. Set your food processor to medium speed and blend until fully combined. You’ll want to ensure everything is creamy and smooth, so don’t be afraid to blend a little longer!
Step 5: Adjust Seasoning
Taste your heavenly mixture and adjust the seasoning as needed. A touch more salt could elevate the flavor, or perhaps more erythritol if you like it sweeter. Blend again until fully mixed.
Step 6: Roll it Up
Spoon your luscious butter onto a sheet of cling film and gently roll it into a log shape. Twist the ends to seal properly and make it look professional. Pop it into the fridge to chill for at least an hour, or towards a 3-day glory in the freezer!
After all that hard work, it’s time to savor the result! Slice off some from your chilled French Onion Compound Butter log and spread it atop a warm piece of bread, perhaps even over grilled vegetables or a steak for a flavor boost that leaves everyone begging for the recipe. You’ll find that once you have this compound butter in your kitchen arsenal, you may just want to whip up another batch for every meal. Enjoy!
