Easy Vegan French Onion Dip

I made this dip because I had an entire bag of sad, soft onions and a craving for something creamy and a little naughty — but totally plant-based. It’s a no-fuss vegan French onion dip that tastes like bar food and holiday spread had a genius baby: deeply caramelized onions, tangy dairy-free base, a little umami punch, and chips don’t stand a chance.

My husband LOVES this. He’ll sneak into the kitchen with a spoon (no chips — savage) and give me the look like I’ve outdone myself. Our kid calls it “the brown stuff” and will eat it on carrot sticks like it’s dessert. It’s become our go-to for movie nights, potlucks, and a quick “I forgot to buy groceries” rescue strategy.

I learned the hard way that caramelizing onions is about patience, not power. Crank the heat and you’ll have blacked bits and a sulky pan. Low and slow makes them sing: sweet, sticky, almost jammy. Once I accidentally used maple syrup to speed things up (don’t do that unless you want a weirdly breakfast-y dip). The best swap that actually worked was a splash of tamari at the end — it wakes up the onions without tasting like soy sauce. Also: if your blender or food processor is small, do the creamy base first and blend the onions in batches, or you’ll be elbow-deep in onion sludge at midnight.

Shopping Tips

– Vegetables: Use yellow or sweet onions for the best caramel flavor; avoid super-juicy white onions that can make the dip watery.
– Fats & Oils: Olive oil is fine, but a little vegan butter (or a mix) gives a richer, more indulgent finish.
– Spices: Smoked paprika and a little dried thyme are nice; buy small jars if you don’t use them often.
– Specialty Item: Nutritional yeast or a vegan parmesan substitute adds cheesy umami — don’t skip it if you want that “French onion” vibe.
– Nuts & Seeds: If using soaked cashews for creaminess, get raw, unsalted ones for a neutral base.

Prep Ahead Ideas

– Caramelize the onions a day or two ahead and store in an airtight container in the fridge — they actually taste better after a day.
– Make the creamy base (cashew cream or vegan yogurt + mayo) and chill separately; combine right before serving so the texture stays lively.
– Store in shallow containers so everything cools quickly; label with the date. On weeknights, toss the two parts together and slice some veggies — dinner is five minutes of assembly.

✔Time-Saving Tricks

– Use a heavy-bottomed pan and cook onions at medium-low while you do other things — they need space to breathe more than your constant stirring.
– Shortcut: thinly slice onions by hand or use a mandoline; faster caramelizing when slices are even.
– Swap soaked cashews for full-fat canned coconut milk in a pinch (taste will be slightly tropical).
– Don’t rush the caramelization — the flavor cannot be hurried, but you can prep everything else while they do their thing.

✔Common Mistakes

– Burned onions: I once tried to rush them with high heat and ended up tossing half the pan. If they’re sticking and blackening, lower the heat and add a splash of water to deglaze.
– Watery dip: often from un-drained yogurt or wet onions — let hot onions cool a bit and drain excess liquid from any plant yogurts.
– Blandness: under-seasoning is the enemy. Taste after mixing and add salt, acid (lemon or vinegar), or a touch more nutritional yeast to brighten.
– Over-blending: puree can get gluey; pulse to keep a little texture if you like bite.

What to Serve It With

– Classic: sturdy potato chips or kettle chips for maximum crunch.
– Veg-forward: carrot sticks, celery, and cucumber slices for lighter snacking.
– Sandwich upgrade: slather on a roasted mushroom or tempeh sandwich.
– Party tray: pair with olives, pickles, and warm pita or crusty bread.

✔Tips & Mistakes

– Use medium-low heat for onions — low and patient wins.
– Add acid (a splash of sherry vinegar or lemon) at the end to lift flavors.
– If dip is too thin, whisk in more blended cashews or a spoonful of vegan mayo.
– If it’s too salty, stir in more plain yogurt or a dollop of mashed potato to calm it down.

✔Storage Tips

Store leftover dip in an airtight container in the fridge for up to 4–5 days. Flavors actually meld and get better after a night in the fridge. Yes, you can eat it cold — I’ve sat with a tub and a spoon before and I won’t judge you. It also makes a killer savory breakfast spread on toast with avocado if you’re feeling wild.

✔Variations and Substitutions

– Swap cashew cream for thick unsweetened vegan yogurt or silken tofu if you want a lower-fat version.
– For gluten-free, serve with GF crackers or veggies.
– Want smokiness? Add a pinch of smoked salt or chipotle powder.
– No nutritional yeast? A dash of miso adds a savory lift (use less salt elsewhere).
– Olive oil vs. vegan butter debate: butter = richer, olive oil = brighter.

Ingredients

 

1x2x3x

Main Ingredients

• ▢ 3 cup thinly sliced yellow onions from about 2 medium onions
• ▢ 1.5 tbsp olive oil or avocado oil
• ▢ 1 tbsp plant-based butter optional, for richer flavor
• ▢ 1 cup dairy-free sour cream store-bought or homemade
• ▢ 0.5 cup vegan mayonnaise
• ▢ 1 tsp onion powder
• ▢ 0.5 tsp garlic powder
• ▢ 1.5 tsp fresh lemon juice
• ▢ 1 tsp tamari (or vegan Worcestershire)
• ▢ 0.75 tsp kosher salt plus more to taste
• ▢ 0.25 tsp freshly ground black pepper
• ▢ 2 tbsp finely chopped fresh chives plus extra for garnish
• ▢ 0.5 tsp granulated sugar balances the onions

Instructions

Preparation Steps

• Warm the oil and butter in a large skillet over medium heat.
• Add the onions and a pinch of salt. Cook, stirring often, until deep golden and jammy, 20–25 minutes. Splash in water as needed to prevent scorching.
• Transfer onions to a plate and let cool until just warm.
• In a mixing bowl, whisk sour cream, mayo, onion powder, garlic powder, lemon juice, tamari, remaining salt, pepper, and sugar until smooth.
• Fold in the cooled onions and chives. Taste and adjust seasoning.
• Cover and chill at least 30 minutes for flavors to meld. Garnish with extra chives before serving.

Notes

For extra umami, whisk in 1 tsp white miso or a dash more tamari. Make it lighter by swapping half the mayo for unsweetened plain vegan yogurt. Serve with kettle chips, pretzels, or crisp veggies; it also makes a great sandwich spread. Store refrigerated in an airtight container for up to 4 days.
