A quick, budget-friendly Kabsa (Saudi spiced rice dish) made with canned tuna, layer-style: the tuna mixed with olives, green pepper, and lemon at the bottom of the pot, basmati rice over it, then curry-spiced water bringing the dish together in twenty minutes. The end-of-month dinner that gives up nothing of Kabsa's flavor.
The original is the tuna Kabsa recipe from Atyab Tabkha, kept in its layered method as is: the tuna, olive, and lemon mixture at the bottom, the rice over it, curry water poured over both, and the pot flipped at serving.
We kept the quantities and steps to the original and adjusted two things: the salt became a gram-measured minimum instead of "to taste," and the servings became six instead of four so the rice portion stays within a sensible bound for an everyday rice dish.
In the bottom of a medium pot, mix the drained flaked tuna with the garlic, olives, green onion, bell pepper, lemon juice, thyme, black pepper, half the curry powder, and half the salt, and stir two minutes until the mixture is uniform and the lemon coats the tuna, softening its smell.
Spread the soaked, drained rice over the tuna mixture in an even layer using the back of a spoon, without any mixing — keeping the two layers separate before cooking is what stops the tuna from crumbling into the rice and keeps the Kabsa's heart tidy at serving.
In a jug, mix the boiling water with the remaining curry powder, remaining salt, onion powder, and olive oil, and pour it slowly down the side of the pot so it covers the rice without digging into the layers, the water taking on the curry's yellow color.
Set the pot over high heat two minutes until the boil returns, then lower the heat to its gentlest, cover, and cook 20 minutes until the rice absorbs all the water, small steam holes appear on its surface, and the grains separate.
Turn off the heat and let the pot rest 5 minutes covered, then place the serving platter over the pot and flip it in one steady motion so the tuna and vegetables become the face of the Kabsa. Serve hot with a green salad or daggus (Gulf tomato-chili sauce).
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.
A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.

The most common problems when preparing Tuna Kabsa, and how to fix them:
The tuna was not drained well, or the lemon fell short. Press the tuna in the strainer until all the can liquid is out, and keep to the half cup of lemon juice — it is the one tasked with softening the smell, together with the thyme.
The water was poured too hard, or the pot was stirred during cooking. Pour the water slowly down the side of the pot — over the back of a spoon if needed — and never stir after spreading the rice; the layers set on their own with the steam.
The heat stayed too high after the boil. Two minutes only on high, then the lowest possible setting — and a heavy-bottomed pot protects the tuna layer from sticking and burning.
Too little curry powder, or an old jar that lost its aroma. Divide the curry in half as the method says: half with the tuna and half in the water, so the aroma spreads through both layers instead of sitting in one.
Keep in an airtight container up to two days only — seafood dishes have a shorter life than meat and chicken Kabsas.
Not preferred: flaked tuna gets drier with freezing and reheating. Better to cook the amount eaten today and tomorrow.
Reheat with a sprinkle of water, covered, over low heat just until hot — and one reheat only, no more.
Cooked rice must not sit at room temperature more than two hours; chill it quickly, following the two-hour rule.
| Original Ingredient | Tested Substitute | Ratio | Flavor Difference |
|---|---|---|---|
| Canned tuna | Canned salmon, drained | Same weight, 400 g | A richer flavor and more omega-3, and the dish stays a budget-friendly canned-seafood meal. |
| White basmati rice | Brown basmati, soaked an hour | Same weight, 400 g, with 150 ml more water | More fiber and a gentler effect on blood sugar; needs 15 extra minutes of cooking. |
| Onion powder | A small grated onion sauteed in the oil first | 80 g in place of 6 g powder | A flavor closer to fresh at the cost of one sauteing step, and it slightly raises the dish's vegetables. |
| Black olives | Omit them | No substitute | Lowers the dish's sodium; the bell pepper and green onion make up for their presence in the texture. |
| Servings | Tuna | Rice | Water |
|---|---|---|---|
| 3 servings (half amount) | 200 g | 200 g | 375 ml |
| 6 servings (base) | 400 g | 400 g | 750 ml |
| 9 servings (1.5x) | 600 g | 600 g | 1125 ml |
Water-packed canned tuna is lighter than oil-packed and spares fat the dish does not need — its flavor comes from the curry, lemon, and olives, not the can's oil. And squeeze the lemon fresh at prep time, not earlier; that fresh acidity is what cuts the canned-tuna smell.
