Ingredients for spam and egg onigiri
Here's what you'll need to make these crispy, savory Japanese rice bites.
| Ingredient | Amount | Notes |
|---|---|---|
| Japanese Short-Grain Rice 🍚 | 2 cups | Uncooked, sushi rice preferred |
| Water 💧 | 2 ¼ cups | For rice cooking ratio |
| Spam 🥓 | 8 oz | Diced into 1/2-inch pieces |
| Large Eggs 🥚 | 2 whole | Scrambled for filling |
| Butter 🧈 | 2 tbsp | Unsalted for scrambling eggs |
| Soy Sauce 🍶 | 1 ½ tbsp | For rice seasoning |
| Rice Vinegar 🍶 | ½ tbsp | For rice seasoning |
| Sesame Oil 🫒 | ½ tbsp | For finishing rice |
| Toasted Sesame Seeds 🌾 | 1 tbsp | For garnish |
| Vegetable Oil 🫒 | 2 tbsp | For frying onigiri |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Green Onions 🧅 | 2 whole | Thinly sliced for garnish |
The rice is everything—Japanese short-grain is non-negotiable for that perfect sticky texture. Sushi rice from Trader Joe's or Asian markets is your best bet, but any short-grain rice works in a pinch. For the filling, Hormel Spam (the classic kind) gives that unmistakable umami crunch. I always buy extra because it disappears fast. The eggs? Fresh, cold eggs scramble the best—whisk them well before cooking for that silky texture. Don't skip the soy sauce and rice vinegar on the rice; that's what makes it taste authentic.
No sushi rice? Jasmine rice is your next best option, though it won't be quite as sticky. Short on soy sauce? Coconut aminos in a 1:1 ratio works, but you'll lose that classic umami depth. The sesame oil is optional but adds that nutty aroma—Kadoya brand is my go-to. For the eggs, if you prefer them runnier, add an extra yolk. The green onions are just for garnish, but if you're feeling fancy, swap them for shredded nori strips. And yes, you can make these ahead—they reheat beautifully, though the crispy bits soften a bit.
Cooked rice keeps for 3 days in the fridge, but it dries out fast, so store it in an airtight container with a damp paper towel. The scrambled egg filling can be made a day ahead and stored separately. For the best texture, shape the onigiri right before frying or steaming. If you're making a batch for later, steam them instead of frying—they'll hold up better. These freeze surprisingly well too: wrap individually in plastic wrap, then freeze for up to 1 month. Just thaw and reheat gently.
Why You'll Love This Recipe
- Five-Ingredient Magic: I swear by this combo—rice, spam, eggs, butter, and water. That’s it. No fancy prep, no hidden pantry items. The rice soaks up the salty-savory spam while the eggs add that rich, buttery bite. It’s the kind of recipe that makes me wonder why I ever complicate things.
- Salty-Sweet Crunch: The spam’s smoky depth pairs perfectly with the soft, buttery egg filling. Honestly, the first time I bit into one, I nearly dropped my chopsticks. That contrast—creamy egg, crispy edge, sticky rice—is dangerously addictive. (Yes, even on a Tuesday night.)
- Lunchbox Hero: Between us, this is my go-to for packed lunches. Wrap a few in foil, toss them in a bag, and they stay intact for hours. Kids love them, coworkers will stare in envy, and you’ll finally have a lunch that doesn’t involve sad desk salad. No reheating needed—just grab and go.
- Budget Bulk: Spam’s cheap, eggs are a steal, and rice lasts forever. I make a big batch on Sundays, and suddenly I’ve got weeknight dinners covered without breaking the bank. Leftovers? They’re even better the next day—if there are any left. (Spoiler: there won’t be.)
Step-by-step instructions for Spam and egg onigiri
Let's make these savory rice bites with a perfect balance of fluffy rice and flavorful filling.
Cook the Japanese Short-Grain Rice
Rinse the 2 cups of Japanese short-grain rice under cold water until the water runs clear. This removes excess starch that would make the rice gummy. Transfer the rice to a pot with the 2.25 cups of water and bring to a boil over high heat. Once boiling, reduce heat to low, cover tightly, and simmer for 15 minutes.
After 15 minutes, turn off the heat and let the rice steam undisturbed for another 10 minutes. This resting period is crucial—it allows the rice to absorb any remaining moisture and become perfectly fluffy. Avoid lifting the lid during this time, or you'll release steam and end up with dry rice.
Prepare the Spam and Egg Filling
While the rice cooks, dice the 8 oz of Spam into ½-inch pieces. In a nonstick skillet, melt the 2 tbsp of butter over medium heat. Add the Spam and cook for 3-4 minutes until lightly browned and heated through. Transfer the Spam to a bowl and set aside.
In the same skillet, scramble the 2 whole large eggs until just set but still slightly moist. Combine the scrambled eggs with the cooked Spam and mix well. Season with ½ tsp of salt and 1 tbsp of soy sauce. Let the mixture cool slightly before using as filling.
Season and Shape the Onigiri
Once the rice has finished cooking, transfer it to a large bowl. Gently fluff the rice with a fork, then drizzle over the 1.5 tbsp of soy sauce, 0.5 tbsp of rice vinegar, and 0.5 tbsp of sesame oil. Mix gently but thoroughly to distribute the seasoning evenly. The rice should be moist but not sticky.
Wet your hands with water and take about ½ cup of the seasoned rice. Press it firmly into a ball, leaving a small indentation in the center. Spoon about 1 tbsp of the Spam and egg mixture into the indentation, then seal the rice around it. Repeat until all the rice is used, making about 8 onigiri.
Fry for Crispy Texture
Heat 1 tbsp of vegetable oil in a skillet over medium heat until shimmering. Carefully place the onigiri in the skillet, pressing down gently to ensure even contact with the oil. Fry for 2-3 minutes per side until golden brown and crispy. Don't overcrowd the pan, or the oil temperature will drop and the onigiri won't brown properly.
Transfer the fried onigiri to a paper towel-lined plate to drain excess oil. While still warm, sprinkle each onigiri with a pinch of toasted sesame seeds and thinly sliced green onions. Serve immediately while the exterior is still crispy and the filling is warm.
Pro Tips For Making Spam And Egg Onigiri
- CHOP SPAM THIN: I learned this the hard way—thick slices of spam stay rubbery inside onigiri. Aim for ¼-inch slices, then cut them into matchsticks. They’ll cook faster and absorb the egg flavor better. (Yes, it’s tedious, but your onigiri will actually taste good.)
- USE COLD RICE: Warm rice sticks together like glue. Let your cooked rice cool completely before shaping—about 20 minutes at room temp. Cold rice holds its shape better and won’t turn mushy when you press it. (I know, waiting is the worst part.)
- FRIZZ THE EGGS LOW: High heat makes eggs rubbery. Cook them over medium-low in butter until the whites are just set and yolks are still runny—about 3 minutes per side. Warm yolks blend into the rice without breaking the onigiri’s structure. (Your future self will curse you if you overcook them.)
- SALT THE RICE WELL: Japanese short-grain rice needs more salt than you’d think—about 1½ teaspoons per cup of dry rice. Skip this, and your onigiri will taste bland. Add the salt with the water, not after cooking. (I used to eyeball it and wondered why my rice tasted flat.)
Troubleshooting great spam and egg onigiri
Rice Too Dry?
If your rice turns out dry, it’s usually because you lifted the lid too soon or didn’t rest it long enough. Always let the rice steam undisturbed for 10 minutes after cooking—this is non-negotiable for fluffy texture.
Next time, try adding 1 extra tablespoon of water to the initial ratio and use a tight-fitting lid to trap steam. 💧
Filling Too Wet?
Overly wet fillings can make your onigiri fall apart. To fix this, pat the scrambled egg mixture dry with a paper towel before mixing with the Spam. If the filling is still too moist, add 1 extra tablespoon of cooked rice to absorb excess liquid.
For extra insurance, chill the filling for 10 minutes before using—this helps it firm up. 🥚
Onigiri Falling Apart?
Wet hands are key to shaping, but if your rice keeps sticking and breaking, your rice might be too dry or you’re not pressing firmly enough. Rice should be moist but not sticky—adjust with a spray of water if needed.
For extra stability, wrap each onigiri in plastic wrap while shaping, then remove before frying. If using leftover rice, spritz it with water before shaping. 🧂
Not Crispy Enough?
Undercooked exteriors happen when oil temperature is too low. Use a thermometer to keep oil at 350°F—if you don’t have one, test with a breadcrumb: it should sizzle and turn golden in 30 seconds.
For even crispiness, press down gently on each onigiri with a spatula while frying. If your pan is too crowded, fry in batches for better browning. 🔥
Filling Too Salty?
If the Spam and egg combo tastes overpowering, balance it with 1 extra teaspoon of rice vinegar in the rice seasoning. For the filling itself, reduce soy sauce to ½ tablespoon and add a pinch of sugar (½ tsp) to mellow the saltiness.
Freshly scrambled eggs also help dilute the flavor—don’t overcook them to keep them light and tender. 🧈
Storage Solutions
Onigiri lose crispiness when stored, but you can re-crisp them by pan-frying for 1-2 minutes before serving. For best results, store uncooked shaped onigiri in an airtight container with a damp towel to prevent drying.
If reheating, steam for 5 minutes instead of frying to preserve moisture. Freeze extras by wrapping individually in plastic wrap—they’ll keep for 1 month and reheat well. ❄️

Frequently asked questions
Can I make these onigiri without frying?
For a lighter version, steam the shaped onigiri for 5-7 minutes in a bamboo steamer lined with parchment paper. This keeps the rice tender and filling warm without adding oil. You can also bake them at 375°F for 10-12 minutes until golden, brushing lightly with oil first for crispiness.
What's the best way to shape perfect onigiri?
Wet your hands thoroughly and take about ½ cup of rice at a time. Press firmly into a ball, then make a small well in the center with your thumb. Add filling and seal by pinching the sides together. Pro tip: Use a wet kitchen towel under your hands to prevent sticking and create a smooth surface for shaping.
Can I use canned tuna instead of Spam?
Yes, but the flavor will be different. Drain well and mix with 1 tbsp soy sauce and ½ tsp sugar to mimic Spam's saltiness. For texture, add 1 tbsp chopped pickles or ½ tsp furikake to the rice. The onigiri will be lighter but still delicious—just expect a milder umami punch.
How do I keep my onigiri from falling apart when packing for lunch?
Shape them just before packing and wrap each individually in plastic wrap or parchment paper. Store in an airtight container with a damp paper towel to prevent drying. For extra stability, steam them first—this helps the rice hold together better during transport. They'll stay intact for 4-6 hours this way.
What's the secret to getting that restaurant-style crispy exterior?
The key is oil temperature and pressure. Heat oil to 350°F and fry in small batches—overcrowding drops the temp. Press each onigiri gently with a spatula while frying to ensure even contact. For extra crunch, try a double-fry: fry once at 325°F for 2 minutes, then again at 375°F for 1 minute until golden.
