Low FODMAP French Onion Dip Ingredients

“Onion” Flavor Base

• 1 tbsp garlic-infused olive oil (strained, with no garlic pieces)
• 1 cup finely sliced green tops of leeks (green parts only)
• 1/2 cup finely sliced green parts of scallions (spring onions)
• 1/2 tsp asafoetida (hing) powder (optional, check label for wheat)

Creamy Dip Base

• 1 cup lactose-free sour cream
• 1/2 cup lactose-free Greek yogurt (or plain lactose-free yogurt, drained)
• 2 tbsp lactose-free cream cheese, softened (optional, for extra thickness)

Seasonings

• 1–2 tsp Dijon mustard
• 1–2 tsp fresh lemon juice
• 1/2 tsp smoked paprika or sweet paprika
• 2–3 tbsp finely chopped fresh chives
• Salt and freshly ground black pepper, to taste

How To Make Low FODMAP French Onion Dip

1. Cook the greens: Heat the garlic-infused oil in a small skillet over low–medium heat. Add the sliced leek tops and scallion greens with a pinch of salt. Sauté for 8–10 minutes until they are very soft and fragrant. Reduce the heat if they start to brown too quickly.
2. Add the spice: If using asafoetida, sprinkle it into the pan and cook for another 30 seconds while stirring constantly. This releases the savory “onion” aroma. Remove the pan from the heat and let the mixture cool completely.
3. Prepare the creamy base: In a medium bowl, combine the lactose-free sour cream, lactose-free Greek yogurt, and cream cheese. Whisk well until the mixture is smooth and no lumps remain.
4. Season the dip: Stir in the Dijon mustard, lemon juice, smoked paprika, fresh chives, a pinch of salt, and black pepper. Mix everything thoroughly.
5. Add the onion mix: Once the cooked leeks and scallions are cool, fold them into the creamy dairy mixture. Stir until the greens are evenly distributed. Taste the dip and add more salt or lemon juice if desired.
6. Chill for flavor: Cover the bowl and place it in the refrigerator for at least 1 hour. This resting time is crucial for the flavors to blend together.
7. Serve: Transfer the chilled dip to a serving bowl. Top with extra chives or a drizzle of garlic oil and serve immediately.

Recipe Tips

• Stick to the Greens: The white bulb parts of leeks and scallions contain high amounts of fructans, which trigger IBS symptoms. Always discard the whites or save them for family members who do not follow a low FODMAP diet; only use the dark green leaves.
• Cool the Greens: Make sure your sautéed leek mixture is completely cool before adding it to the sour cream. If it is hot, it will melt the dairy and make your dip runny and watery.
• Understanding Asafoetida: Asafoetida (also called Hing) is an Indian spice with a strong smell that mellows into a flavor very similar to onions and garlic when cooked. It is a secret weapon for adding savory depth without actual onions.
• Thicken the Yogurt: If you cannot find Greek-style lactose-free yogurt, you can use regular plain lactose-free yogurt. However, it helps to strain it through a cheesecloth or coffee filter for 30 minutes to remove excess liquid for a thicker dip.

What To Serve Low FODMAP French Onion Dip

This dip is the star of any snack table. Serve it with plain potato chips (check the ingredients to ensure no onion powder is added). It also pairs perfectly with gluten-free pretzels or plain rice crackers.

For a healthier, fresher option, create a crudité platter with low FODMAP vegetables. Great choices include carrot sticks, cucumber rounds, red bell pepper slices, and cherry tomatoes (limit to 5 per serving).

How To Store Low FODMAP French Onion Dip Leftovers

• Refrigerate: Store the dip in an airtight container in the refrigerator for up to 3 to 4 days. You may see a little liquid separate on top after a day; simply stir it back in before serving.
• Freeze: It is not recommended to freeze this dip. Sour cream and yogurt tend to separate and become grainy when thawed, which ruins the creamy texture.

Frequently Asked Questions

• Can I make this ahead of time? Yes, this is actually the best way to do it! Making the dip a day in advance allows the onion and garlic flavors to fully infuse into the cream, making it taste even better.
• Is sour cream low FODMAP? Regular sour cream contains lactose, which is a high FODMAP sugar. However, this recipe specifically uses lactose-free sour cream, which is safe to eat. If you can’t find it, you can make your own by adding lemon juice to lactose-free cream.
• What if I can’t find garlic-infused oil? You can make your own safe garlic oil at home. Sauté large cloves of garlic in olive oil for a few minutes, then remove and discard the garlic cloves entirely before using the oil. The fructans stay in the garlic solid, while the flavor goes into the oil.
