Omurice (Japanese Omelette Rice) — The Ketchup Version We Make at Home

Omurice (オムライス) is Japanese comfort food at its most affectionate — a mound of ketchup-flavored chicken fried rice wrapped in a soft, thin omelette, with a squiggle of ketchup on top. It’s a yoshoku classic, the kind of Western-influenced home cooking that every Japanese kid grows up with and every adult still craves. It looks a little fancy but it’s really just fried rice and eggs, and it comes together from odds and ends in the fridge.

I made this one on the weekend for my wife, which is why there’s a big “LOVE” written in ketchup across the top — that’s a very normal omurice thing to do here, whether it’s a parent writing a kid’s name or a slightly embarrassing husband writing something soppy. Nothing about this is restaurant-perfect: I used up the half onion, green pepper, carrot and mushrooms we had, a pack of konsomé (consommé) powder for seasoning, and a plain everyday plate. This is just how we actually eat it at home.

Why You’ll Love This Recipe

• Comfort food classic. Ketchup chicken rice in a soft omelette — nostalgic, cozy, and always a hit.
• A great way to use up leftovers. Day-old rice and whatever vegetables and chicken you have on hand.
• Simpler than it looks. No fancy tornado-egg skills needed — this is the easy home-style fold.
• Kids (and spouses) love it. Write a name or a message in ketchup and it’s an instant favorite.

What is Omurice?

Omurice is a portmanteau of “omelette” and “rice,” and it’s one of the pillars of yoshoku — Japanese-style Western food that developed in the early 20th century. The classic version is chicken fried rice seasoned with ketchup (we call it chikin raisu), wrapped in a thin omelette and topped with more ketchup. It shows up everywhere in Japan: family kitchens, old-school diners, kids’ lunch plates, and cafes that do elaborate fluffy-egg versions.

Mine is the plain home version — a fully-cooked omelette folded over the rice, not the runny tanpopo style you see on TV. It’s the one most families actually make on a busy evening. If you like this kind of yoshoku comfort food, you’ll probably also enjoy my napolitan (ketchup spaghetti) and Japanese hamburg steak.

Ingredients (Serves 2)

Ingredient	Amount	Notes
Cooked rice	2 bowls (about 400 g)	Day-old rice works best
Chicken thigh	150 g	Cut into small bite-sized pieces
Onion	1/2	Finely chopped
Carrot	1/4	Finely diced
Green pepper	1	Finely chopped
Mushrooms	2–3	Chopped (I used what we had)
Ketchup	4–5 tbsp	Plus more for topping
Consommé powder	1 tsp	Or a crumbled stock cube
Salt & pepper	To taste
Eggs	4 (2 per omelette)	Lightly beaten
Butter	1 tbsp	For the omelettes
Oil	1 tbsp	For the fried rice

The only “special” ingredient here is a good tomato ketchup — it’s what carries the whole dish, so use one you like. I keep a bottle of Japanese ketchup and pantry staples around, but any decent brand works. For the omelette, a small non-stick (fluorine-coated) frying pan of about 20 cm makes all the difference — it’s the right size for a single serving, so the egg sets into a neat wrap, and the coating lets it slide and fold cleanly. A good small non-stick frying pan on Amazon takes all the stress out of this step.

How to Make Omurice

Step 1: Prep the Chicken and Vegetables

Cut the chicken thigh into small bite-sized pieces and finely chop the onion, carrot, green pepper, and mushrooms. Keeping everything small means it mixes evenly through the rice. Use whatever vegetables you have — this is a great fridge-clearing dish.

Step 2: Cook the Chicken

Heat the oil in a pan over medium heat and cook the chicken until it’s lightly browned and just about cooked through. A little color on the chicken adds flavor to the whole dish.

Step 3: Add the Vegetables

Add the onion, carrot, green pepper, and mushrooms and stir-fry until the vegetables are softened and the onion turns translucent. Season with a little salt and pepper as you go.

Step 4: Add the Ketchup

Push the ingredients to the side, add the ketchup to the empty part of the pan, and let it fry for 30 seconds or so. Cooking the ketchup down like this deepens the flavor and takes off the raw, sharp edge — this one step is the secret to good chikin rice.

Step 5: Add the Rice

Add the cooked rice and start folding everything together. Day-old rice is ideal because it’s drier and doesn’t clump. Break up any lumps with the back of your spatula.

Step 6: Season with Consommé

Sprinkle in the consommé powder and stir-fry until the rice is evenly colored and everything is well combined. Taste and adjust with more ketchup, salt, or pepper. You want the rice glossy and orange, with no white patches left.

Here’s the finished chikin rice — evenly orange and packed with chicken and vegetables. Transfer it to a bowl and give the pan a quick wipe before making the omelettes.

Step 7: Start the Omelette

Melt the butter in a clean pan over medium heat. A small non-stick pan of about 20 cm is ideal here — it’s just the right size to wrap one serving, so you don’t have to fight a huge sheet of egg. Once the butter is foaming, pour in the beaten egg (2 eggs per omelette) and swirl to cover the base. Let it set at the edges while the center is still just a little soft.

Step 8: Add the Rice and Fold

Spoon a mound of the chikin rice onto one half of the omelette. Then fold the other half of the egg over the rice to make a half-moon parcel. Don’t worry if it’s not perfect — a home fold like this is completely normal.

Step 9: Turn Out onto the Plate

Slide the omurice out of the pan and onto a plate, seam-side down, so it holds its shape. If you like, you can lay a paper towel over the top and gently shape it into a neat oval with your hands — but honestly, it tastes the same either way.

Step 10: Finish with Ketchup

Finish with a squiggle of ketchup on top — a zigzag, a heart, a name, or, in my case, a big “LOVE” for my wife. This is the fun part, and it’s what makes omurice feel like a little gift on a plate.

Cut it open and you get that classic omurice cross-section — soft yellow egg around warm, orange ketchup rice.

Tips and Variations

• Use day-old rice. Freshly cooked rice is too moist and turns gluey — cold rice from the fridge fries up much better.
• Fry the ketchup. Cooking the ketchup for a moment before adding the rice deepens the flavor and removes the raw tang.
• Use a small pan for the omelette. A non-stick (fluorine-coated) pan of about 20 cm is the sweet spot — big enough to hold one serving, small enough that the egg wraps neatly instead of tearing.
• Induction works fine. I make this on an IH (induction) cooktop — no special heat needed, just keep the omelette on medium so it doesn’t brown.
• Want it soft and runny? For a café-style omurice, slide a barely-set omelette on top of a rice mound and slit it open so it spills over.
• Swap the protein. Ham, sausage, or shrimp all work in place of chicken.

What to Serve It With

Omurice is a full meal on its own, but a simple side or soup rounds it out nicely:

• A bowl of easy miso soup or a light consommé soup.
• A crisp green salad or a daikon salad to cut the richness.
• Serve it diner-style alongside a hamburg steak for a full yoshoku plate.

Storing and Reheating

Omurice is best eaten fresh, but leftovers keep in the fridge for up to a day. Cover and reheat gently in the microwave — the egg firms up a little but the flavor is still good. The ketchup chicken rice on its own also freezes well, so you can make a big batch of the rice, freeze it in portions, and just cook a fresh omelette when you want omurice again.
