Garlic–Onion Chili Soy-Sriracha Corn (Tossed on the Cob) — Detailed Recipe

Serves

2–4 (depending on cob size)

Ingredients

For the corn

2–4 ears corn on the cob (fresh preferred, frozen also works—see notes)
Water + a pinch of salt (optional, for boiling)

For the chili-garlic oil

3–5 tbsp neutral oil (or 1–2 tbsp if you prefer it less saucy)
3–5 cloves garlic, finely minced (or grated)
1/2 small onion, finely diced or thinly sliced
1–2 small chilies (or 1/2–1 tsp chili flakes), finely chopped
Adjust to heat tolerance
1/2–3/4 tsp salt (optional; depends how salty your soy sauce is)
1/2 tsp black pepper (optional)

For the sauce

2 tbsp soy sauce
1–2 tbsp sriracha (to taste)
1–2 tbsp tomato ketchup
Optional: 1 tsp rice vinegar or a squeeze of lime to brighten (highly recommended)

To finish

Cilantro, chopped (generous handful)
Optional: toasted sesame seeds or a squeeze of lime

Step-by-Step Instructions

1) Boil the corn

Bring a pot of water to a boil.
Add a pinch of salt (optional).
Add corn and boil:
Fresh corn: 6–10 minutes (until tender)
Frozen corn-on-cob: ~4–7 minutes
When tender, remove corn and let it cool just enough to handle.

Tip (extra flavor): If you want a “charred” edge, quick-sear afterward—see Variations.

2) Make the garlic-onion chili oil

In a skillet on medium heat, add oil.
Add diced onion and cook 2–4 minutes until soft and lightly golden.
Add garlic and cook 20–45 seconds (avoid burning).
Add chili (fresh chili or flakes). Cook 15–30 seconds until fragrant.

3) Build the sauce

Lower heat to medium-low.
Add soy sauce, sriracha, and ketchup.
Stir well and simmer 30–60 seconds until glossy and cohesive.
Taste and adjust:
More sriracha = more heat
More soy = salt/umami
More ketchup = sweeter/tangier body
Add a few drops of lime/vinegar if it tastes “flat”

4) Toss quickly

Add boiled corn directly into the skillet (or place corn on a plate and spoon sauce over it).
Toss/turn quickly 30–90 seconds so the sauce coats without steaming the corn back down.

5) Garnish and serve

Top generously with cilantro.
Serve hot (great as a snack or side).

Flavor Profile (What it tastes like)

This dish is basically a sticky, spicy, sweet-salty chili-corn with aromatic garlic/onion depth.

Umami & savory: soy sauce
Heat & tang: sriracha + chili
Sweet tomato richness: ketchup
Aromatics: garlic + onion (sweet-savory base)
Fresh lift: cilantro at the end (cuts through the richness)
Overall vibe: “Asian-style chili sauce” corn, similar in spirit to street-corn variants, but with a ketchup/soy/sriracha combo.

Nutrition (Estimated)

Nutrition varies a lot by corn size and how much oil/sauce you use. Below are reasonable estimates per serving if you eat 1 corn cob and use about 1.5–2 tbsp oil total in the toss (not all oil may cling).

Per 1 medium corn cob (with sauce and ~2 tbsp oil used)

Approximate range

Calories: ~230–380 kcal
Carbs: ~45–75 g
Protein: ~6–10 g
Fat: ~8–20 g
Fiber: ~6–10 g
Sodium: can be high (soy sauce drives this; often 500–900+ mg depending on how much soy is used and how much coats the corn)

Key note:

Corn itself is naturally carb-forward and provides fiber and some B vitamins.
Sodium is the big wild card.

Practical Tips / Customizations

Less salty: use low-sodium soy sauce.
Less sweet: reduce ketchup to 1 tbsp.
More restaurant-style gloss: add 1–2 tsp water to sauce in the pan before tossing so it emulsifies and coats better.
Extra kick: add a pinch of smoked paprika or extra chili flakes.
