Spice Level Guide: Chili Oil, Jalapeños & Sriracha—Dial In Your Heat at Pho By Night
When it comes to Vietnamese cuisine, pho is more than just a bowl of noodles—it’s a customizable experience of flavors, aromas, and textures. At Pho By Night in Ottawa, guests often ask about the spice levels: how much chili oil should they add, are jalapeños too hot, or is Sriracha the best option to bring the broth alive? This guide provides a complete breakdown of spice levels, cultural significance, and flavor dynamics so you can dial in your perfect heat when enjoying pho and other Vietnamese favorites.
The Vietnamese Approach to Spice
Balancing Heat and Harmony
Unlike some cuisines that build dishes around fiery spice, Vietnamese cooking focuses on balance. Heat is not the dominant note but rather an accent that enhances freshness, herbs, and umami-rich broths. That’s why condiments like chili oil, sliced jalapeños, and Sriracha are always served on the side—giving diners full control.
Is Vietnamese Food Naturally Spicy?
A common question is whether Vietnamese food is inherently spicy. The truth: most traditional dishes start mild. For example, a steaming bowl of pho broth leans savory and aromatic rather than hot. Diners then personalize their bowl using condiments at the table. This distinction sets Vietnamese cuisine apart from some Asian styles, such as Korean or Thai, which often incorporate spice into the base recipe itself (learn more here).
Chili Oil: Smoky, Bold, and Customizable
What It Adds
Chili oil is made by infusing vegetable oil with dried chili flakes, garlic, and sometimes star anise or cinnamon. At Pho By Night, chili oil delivers:
- Deep smokiness that complements beef broth.
- Lingering heat that builds with each spoonful.
- Aromatic undertones that tie in with Vietnamese spices.
How to Use It
- Start small—half a teaspoon can change the profile of your broth.
- Stir thoroughly so the oil blends into the noodles and broth.
- Combine with lime juice and basil for a multi-dimensional kick.
Chili oil is the go-to for diners who want layered spice rather than sharp bursts.
Jalapeños: Fresh Heat with a Crunch
Flavor Profile
Sliced jalapeños bring brightness and crisp texture to pho. Unlike chili oil, jalapeños release heat in quick, sharp bursts when bitten into. They’re particularly popular with diners who enjoy a fresh, raw edge.
Customizing with Jalapeños
- Add one or two slices first, then increase gradually.
- Pair with Thai basil and bean sprouts for a refreshing contrast.
- If you’re spice-sensitive, remove the seeds to tone down intensity.
For those wondering whether Vietnamese food caters to gluten-free or plant-based needs, the good news is jalapeños are naturally gluten-free and vegan-friendly—perfect for diners with dietary restrictions (explore more gluten-free options here).

Sriracha: The Sweet-and-Spicy Staple
Why It Works with Pho
Sriracha is globally recognized, but it originated from Southeast Asia, making it a natural fit at Vietnamese tables. It brings:
- Tangy sweetness that balances pho’s savory broth.
- Medium heat that’s approachable for most diners.
- Versatility—it can be mixed into broth, drizzled on meats, or paired with spring rolls.
Best Pairings
- A squirt in the broth for overall warmth.
- Dipping sauce with hoisin for a sweet-spicy blend.
- Mixed with lime juice for tangy chili sauce.
Unlike chili oil or jalapeños, Sriracha offers a predictable level of spice, making it ideal for newcomers adjusting their palates.

Comparisons Across Asia
When comparing Vietnamese food with other cuisines, Korean food tends to be more spice-forward (like kimchi and gochujang-based stews), while Vietnamese food maintains a lighter, herb-driven balance (see differences here).
Health Benefits of Spice
Adding chili-based condiments isn’t just about flavor—it can also support wellness:
- Capsaicin, found in jalapeños and chili oil, may boost metabolism.
- Spices can help clear nasal passages and aid digestion.
- A moderate amount of spice may reduce inflammation, according to National Institutes of Health studies.
For diners seeking health-conscious options, Vietnamese food naturally aligns with balanced, fresh eating (read more here).
