The Ultimate Comfort Side Dish: Rice Cooked in Onions (Soubise)
Looking for a show-stopping side dish that’s secretly simple? Meet Soubise, a classic French preparation where rice is slow-cooked in a mountain of sweet, tender onions until it becomes unbelievably creamy and flavorful. This recipe, inspired by the great Julia Child, has become a holiday staple in my kitchen, especially for Thanksgiving. It holds its heat beautifully, and if the bottom gets a little crispy and brown, it’s even better!
I’ve updated the classic with a few modern touches: fragrant basmati rice for a delicate texture, a pinch of saffron for a gorgeous golden hue, and a slightly lighter hand with the butter (though you can certainly indulge!). The result is a luxurious, deeply savory dish that tastes like it took hours of effort, but is mostly hands-off. Don’t be intimidated by the number of onions—they melt down into a sweet, silky sauce that cradles every grain of rice.
Ingredients
• • Salt and freshly ground black pepper, to taste• 3-6 tablespoons / 45-85g unsalted butter• 1 cup / 200g basmati rice• 4-5 large onions (about 6-8 cups / 900g-1.2kg), thinly sliced• Large pinch saffron threads (optional)• 1/2 cup / 120ml heavy cream (optional)• Fresh parsley, chopped, for garnish
Instructions
1. Bring a medium saucepan of water to a boil and salt it generously.2. While the water heats, melt 3 tablespoons of butter in a large, deep skillet or casserole with a tight-fitting lid over medium heat.3. Add the rice to the boiling water and cook, stirring occasionally, for about 5 minutes, just until it loses its raw translucence. Drain the rice well, leaving it a little wet.4. Add the sliced onions to the melted butter along with a large pinch of salt and some pepper. Cook, stirring occasionally, for about 5 minutes until the onions just begin to soften.5. Add the drained rice to the onions, along with the saffron threads if using. Stir to combine everything, then turn the heat to the absolute minimum and cover the pan.6. Cook for about 45 minutes, stirring every 15 minutes or so to prevent sticking. For the final 10-15 minutes, do not stir to allow a delicious golden-brown crust to form on the bottom.7. Check that the onions are very soft and the rice is fully cooked. Taste and adjust seasoning with more salt and pepper. Stir in the heavy cream and/or any remaining butter if you desire extra richness. Heat through gently.8. Turn off the heat and let the dish rest, covered, for at least 10 minutes before serving. Garnish with fresh parsley and enjoy.

Pro Tips
• for Perfect Soubise• Use a food processor with the slicing disk attachment to slice the onions uniformly and quickly, saving you time and tears.• Don’t skip the final resting period. This allows the flavors to meld and the rice to absorb any final moisture, resulting in a perfect texture.• For an even sweeter, deeper flavor, use sweet onions like Vidalia or Walla Walla.• Embrace the crust! That browned layer at the bottom of the pan is full of concentrated flavor and adds a wonderful textural contrast.• This dish holds its heat exceptionally well, making it a perfect make-ahead option for dinner parties or holidays. It can be kept warm over a very low flame or gently reheated.
