Cajun Rice on the Blackstone: Easy Griddle Recipe

Cajun rice on the Blackstone is a savory griddle meal made with cooked rice, smoky andouille sausage, the classic onion, bell pepper, and celery combination, and Cajun spices. The hot flat top gives the rice lightly crisp edges while keeping the vegetables tender, and everything cooks together for an easy dinner inspired by Louisiana-style Cajun cooking.

Ingredients

5 cups (about 800 g) cooked, cold long-grain white rice
12 oz (340 g) fully cooked andouille sausage, sliced into ¼-inch (6 mm) rounds
1 cup (150 g) finely diced yellow onion
1 cup (150 g) finely diced green bell pepper
½ cup (75 g) finely diced red bell pepper
1 cup (100 g) finely diced celery
2 tablespoons (30 ml) neutral high-heat oil, such as canola or avocado oil, divided
2 tablespoons (28 g) unsalted butter
1 tablespoon (9 g) minced garlic, about 3 cloves
2 teaspoons (6 g) Cajun seasoning, plus more to taste
1 teaspoon (2 g) smoked paprika
½ teaspoon dried thyme (about 0.5 g)
½ teaspoon ground black pepper (about 1 g)
¼ teaspoon fine salt (about 1.5 g), plus more only if needed
⅓ cup (80 ml) low-sodium chicken broth
⅓ cup (35 g) sliced green onions
2 tablespoons (8 g) chopped fresh parsley, optional
1 lemon, cut into wedges, for serving

Instructions

Prepare the rice and vegetables. Break up the cold rice with clean hands or a fork so there are no large clumps. Dice the onion, bell peppers, and celery to a similar size, mince the garlic, and slice the sausage. Measure the seasonings and broth before heating the griddle. The recipe assumes the rice is already cooked and chilled; preparation and chilling time for rice are not included in the recipe time.
Heat the Blackstone. Preheat the griddle over medium heat for about 5 minutes. Set up a hotter cooking area and a cooler holding area if your griddle has multiple burners. Add 1 tablespoon (15 ml) oil to the hot zone and spread it into a thin film. The surface should shimmer, but the oil should not smoke heavily. If it smokes, reduce the heat briefly before adding food.
Brown the sausage. Add the sliced andouille in a single layer and cook for about 4 minutes, turning the pieces once or twice so they brown on both sides. If using fully cooked sausage, heat it to 165°F (74°C), the USDA FSIS temperature for reheated food, checked with a food thermometer in a larger piece. Move the sausage to the cooler zone or a clean plate while you cook the vegetables. Keep any drippings on the griddle for flavor, but wipe away excess grease if the surface is very oily.
Cook the vegetables. Add the remaining 1 tablespoon (15 ml) oil to the hot zone. Add the onion, green and red bell peppers, and celery. Spread them out and cook for about 5 minutes, turning and scraping with a metal spatula every minute or so. Aim for vegetables that have softened but still hold their shape; if they begin to char before softening, move them toward the cooler area or lower the heat.
Add the garlic and spices. Push the vegetables together and add the butter. When it melts, stir in the garlic, Cajun seasoning, smoked paprika, thyme, black pepper, and salt. Cook for about 1 minute, stirring constantly so the garlic becomes fragrant without burning. Return the sausage to the vegetable mixture and toss to distribute the seasoning.
Griddle the rice. Add the cold rice in two or three handfuls, breaking up clumps as you go. Use the spatula to fold the rice with the sausage and vegetables, then spread it in a fairly thin layer over the hot zone. Cook for about 6 minutes, tossing and spreading it again every minute. Let it sit against the hot surface between turns so some grains toast, but keep it moving often enough to prevent scorching. If your griddle is crowded, work in two batches and combine them at the end.
Season and finish. Drizzle the chicken broth over the rice and toss for about 1 minute, scraping up any browned bits. The broth should be absorbed quickly; the finished rice should be moist and separate, not soupy. Taste a spoonful and add a little more Cajun seasoning or salt if needed, keeping in mind that andouille and seasoning blends can already be salty. Fold in the green onions and parsley, if using, and serve hot with lemon wedges.

Tips

Start with properly chilled rice. Cold rice is drier and less sticky than freshly cooked rice, so it is easier to spread and brown on a griddle. Cook it ahead, fluff it, and cool it promptly in a shallow container. Refrigerate it within 2 hours; do not leave cooked rice on the counter to cool for an extended period. If the grains are tightly packed after chilling, loosen them before they hit the griddle.

Control salt and heat. Cajun seasoning blends vary widely in saltiness and spice. Begin with the listed amount, then taste after the broth has been added. For a milder pan, use a low-sodium seasoning blend or start with 1 teaspoon (3 g) and add more at the end. For more heat, add cayenne in small pinches rather than pouring in extra seasoning blend, which can make the dish too salty.

Keep the rice in contact with the hot surface. A pile of rice steams instead of toasting. Spread it out, cook in batches if necessary, and let it sit briefly before tossing. Avoid pressing it hard into the griddle, which can compact the grains. If the rice looks dry, use a tablespoon of broth at a time; adding too much at once makes it wet and soft.

Choose a practical sausage substitute. Smoked andouille gives the dish its characteristic peppery, smoky flavor. If it is unavailable, use another fully cooked smoked sausage, such as kielbasa, and add Cajun seasoning to taste. The result will be less specifically Cajun in flavor, so a small pinch of cayenne or extra smoked paprika can help, but neither is a perfect replacement for andouille.

Serving Suggestions

Serve the rice straight from the griddle while the edges are still lightly crisp. Lemon wedges add a bright contrast to the rich sausage, and extra sliced green onions or parsley provide a fresh finish. For a simple meal, pair it with a green salad, sliced tomatoes, or grilled vegetables. It also works as a hearty side for grilled chicken, blackened fish, or roasted vegetables; if serving it alongside another seasoned main, keep the rice’s extra Cajun seasoning modest.

For a casual gathering, transfer the rice to a warm serving dish and set out hot sauce and lemon so everyone can adjust their portion. Keep the dish hot rather than leaving it at room temperature for a long serving period. If you are making several griddle batches, combine them on the cooler zone and toss briefly before serving so the sausage and vegetables are distributed evenly.

Variations

Make it without sausage: Leave out the andouille and use an extra tablespoon (15 ml) of oil or butter. For more substance, add 1½ cups (240 g) drained cooked red beans near the end, folding them in gently so they do not mash. The beans make the dish more filling and soften the smoky character; a little smoked paprika can help replace some of the sausage flavor.

Add shrimp: Use 1 pound (450 g) peeled, deveined shrimp in place of the sausage, or combine 8 ounces (225 g) shrimp with 6 ounces (170 g) sausage. Cook shrimp on a clean, lightly oiled area of the griddle until opaque and 145°F (63°C) at the thickest part, checked with a food thermometer. Set it aside while cooking the vegetables and rice, then fold it back in at the end so it does not overcook.

Change the vegetables: Finely diced jalapeño can add a sharper heat; remove its seeds and membrane for a gentler result. A handful of sliced okra can be cooked with the onion and peppers, though it adds a more distinctly Southern texture. You can also use all green bell pepper if that is what you have, but the red pepper contributes sweetness and color.

Use brown rice: Substitute 5 cups (about 800 g) cooked, chilled long-grain brown rice. Its firmer, nuttier grains hold up well on the griddle, though they may need a splash more broth and a minute or two longer to warm through. Avoid substituting uncooked rice: it will not cook properly in the short time the ingredients spend on the griddle.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking, in a shallow airtight container. The rice keeps for 3 to 4 days in the refrigerator. Do not store it in a warm griddle or leave it out while serving; cooked rice needs prompt chilling. For longer storage, freeze portions in airtight freezer-safe containers for up to 2 months for best quality. Thaw frozen portions in the refrigerator before reheating when possible.

Reheat only the portion you plan to eat. On the Blackstone, warm it over medium heat with a teaspoon or two of water or broth, tossing until evenly hot. A skillet or microwave also works; cover loosely in the microwave and stir partway through. Reheat leftovers to 165°F (74°C), checked with a food thermometer, as recommended by USDA FSIS. Add fresh green onion or a squeeze of lemon after reheating to brighten the flavor.

Frequently Asked Questions

Can I use freshly cooked rice? You can, but freshly cooked rice is softer and wetter, so it is more likely to clump and steam rather than toast. If that is your only option, spread the rice in a thin layer on a tray and let excess steam escape, then refrigerate it promptly until cold. Do not leave it at room temperature for more than 2 hours, and avoid putting warm rice into a crowded container where it cools slowly.

What kind of rice works best? Long-grain white rice is a reliable choice because its cooked grains tend to stay separate. Jasmine rice also works, though its aroma is more pronounced. Medium-grain rice is usually softer and stickier, so handle it gently and expect less distinct grains. Whatever variety you choose, use fully cooked, chilled rice rather than uncooked rice.

Can I make Cajun rice on a regular stovetop? Yes. Use a large, heavy skillet or flat-bottomed wok over medium-high heat, and cook the sausage and vegetables in batches if the pan is crowded. Add the rice and spread it across the pan to encourage browning. A regular skillet may not have the same broad cooking surface as a Blackstone, but the ingredient order and seasoning remain the same.

Why is my griddle rice mushy? The most common causes are warm or freshly cooked rice, too much broth, and overcrowding. Use cold rice, add the measured broth only near the end, and cook in batches when needed. If the rice is already cooked but wet, spread it out and give it time on the hot surface before adding anything else; stirring constantly can also prevent the grains from drying and browning.

Is Cajun seasoning the same as Creole seasoning? They are related spice blends, but recipes and brands differ. Cajun blends often emphasize pepper and heat, while some Creole blends include a broader mix of herbs. Either can work in this recipe, but taste before adding extra salt or spice. Louisiana cooking has many regional and family variations, so adjust the seasoning to your preference rather than treating one blend as mandatory.
