Have You Tried Adding an Egg Yolk to Your Morning Coffee? A Simple Twist on a Traditional Vietnamese Dri

 Many people start their day with coffee but still feel foggy-headed and low on energy by mid-morning. That familiar slump hits around 10 a.m., leaving you reaching for another cup or a snack just to stay alert. It’s frustrating when your mornings feel rushed and unproductive, especially as daily demands pile up.

The good news is there’s a traditional Vietnamese-inspired morning ritual that many are exploring for a creamier, more satisfying coffee experience. Keep reading to discover how this easy addition might change your routine—and why it’s worth trying for yourself.

What Is Vietnamese Egg Coffee?

Vietnamese egg coffee, known as cà phê trứng, originated in Hanoi during the 1940s when milk was scarce. A creative barista began whipping egg yolks as a substitute, creating a rich, frothy topping for strong coffee.

Today, it’s a beloved drink in Vietnam, often compared to a liquid dessert for its velvety texture. The base is robust dark coffee, topped with a sweetened egg yolk foam. Many enjoy it hot or iced, and it’s gaining popularity worldwide as people seek unique ways to enhance their daily brew.

Research shows that egg yolks provide nutrients like protein and healthy fats, which can contribute to a feeling of fullness when paired with meals.

Why People Are Exploring Egg in Their Coffee

The appeal lies in the combination of caffeine with the natural components of egg yolk. Proteins and fats from food can influence how quickly caffeine enters the bloodstream, potentially leading to a more gradual energy release.

Studies on breakfasts including eggs suggest they may support steady blood sugar levels compared to carb-heavy options, helping avoid sharp dips in energy. One study found that men who ate eggs for breakfast experienced less variation in plasma glucose and reduced energy intake over 24 hours.

Additionally, egg yolks are one of the richest sources of choline—a nutrient involved in brain function. Choline supports the production of acetylcholine, a neurotransmitter linked to focus and memory. Research indicates that natural choline from egg yolks is efficiently absorbed by the body.

But that’s not all—many report the drink feels more indulgent, like a cafe treat without extra stops.

Potential Benefits You Might Notice from This Morning Habit

People who try egg coffee often share anecdotal experiences about their mornings. Here’s what some commonly mention, backed by general nutrition insights:

• Creamier texture and richer taste: The whipped yolk creates a foam that transforms plain coffee.
• Supported satiety: Protein and fats may help you feel satisfied longer, reducing mid-morning hunger.
• Gradual energy: Fats can slow caffeine absorption for a smoother lift.
• Nutrient boost: One egg yolk delivers about 6g protein, healthy fats, and over 100mg choline.

Research on egg consumption shows:

• Greater feelings of fullness after egg-based meals.
• Potential for stable blood sugar when combined with other foods.
• Choline’s role in cognitive support.

Of course, individual experiences vary, and this isn’t a one-size-fits-all solution.

Nutritional Comparison: Plain Coffee vs. Egg Coffee

Aspect	Plain Black Coffee	Coffee with Whipped Egg Yolk
Protein	~0g	~6g
Healthy Fats	None	From yolk (including omega-3s in some eggs)
Choline	None	~125-150mg (about 25-30% daily needs)
Texture	Thin	Creamy and frothy
Calories (approx., without sweetener)	~2 per cup	~70-100 extra from yolk

How to Make Vietnamese-Style Egg Coffee at Home

This takes just a few minutes once you get the hang of it. Here’s a simple, safe method:

1. Brew strong coffee: Use 8-12 oz of your favorite brew (robust robusta beans are traditional for authenticity).
2. Prepare the egg foam: Separate 1 fresh egg yolk (use pasteurized eggs for added safety). Add 1-2 tsp sweetened condensed milk or a touch of honey.
3. Whisk vigorously: Use a hand frother, whisk, or mixer for 2-3 minutes until thick and fluffy (like soft peaks).
4. Temper if needed: Add a splash of hot coffee to the mixture and whisk to prevent curdling.
5. Assemble: Pour the foam over the hot coffee. Stir gently before drinking.

Pro tips:

• Start with just the yolk for smoother results.
• For iced version, brew coffee over ice and top with foam.
• Adjust sweetness to taste—many reduce it over time.

Studies emphasize using fresh or pasteurized eggs to minimize any food safety concerns.

Common Variations to Try

• Add a dash of vanilla for extra flavor.
• Use whole egg for more volume (though yolk-only is classic).
• Top with cocoa powder for a mocha twist.

Safety Considerations and Best Practices

Egg coffee involves lightly heated or raw egg yolk, so safety matters. While rare, raw eggs can carry risks like salmonella. To stay safe:

• Choose pasteurized eggs whenever possible.
• Use fresh, refrigerated eggs and proper hygiene.
• Vulnerable groups (elderly, pregnant, immunocompromised) should consult a doctor or avoid raw/lightly cooked eggs.

Hot coffee helps warm the mixture, but it’s not a full cook. Many recipes include steps to gently heat the foam.

Frequently Asked Questions

Is egg coffee safe to drink every day?
For most healthy adults using pasteurized eggs and good practices, yes—it’s a traditional drink enjoyed regularly in Vietnam. Always prioritize food safety.

Will it really change my energy levels?
Experiences vary, but the protein-fat-caffeine combo may support steadier mornings for some, as suggested by breakfast studies on eggs.

Can I make it without condensed milk for fewer calories?
Absolutely—use a low-calorie sweetener or skip it. The foam still works with just yolk and a bit of whisking.

Final Thoughts

Exploring a whipped egg yolk in your coffee is a fun way to mix up your morning while adding nutrients like protein and choline. It’s rooted in tradition, easy to prepare, and might just make your brew more enjoyable.
