March 21, 2026

Get ready to fall in love with grits all over again! We’re taking this humble Southern staple and transforming it into a show-stopping Cheesy Jalapeño Grits Casserole. Imagine a creamy, savory bake, loaded with sharp cheddar cheese and a delightful kick from fresh jalapeños, all baked to golden-brown perfection. It’s the ultimate comfort food—equally at home at a festive brunch table as it is a cozy weeknight dinner. This dish is rich, satisfying, and surprisingly simple to whip up. Let’s get cooking!

Ingredients

• 4 cups / 960 mL water
• 1 cup / 170 g quick-cooking hominy grits
• 4 large eggs, lightly beaten
• 2 cups / 226 g shredded cheddar cheese
• 1/2 cup / 120 mL milk
• 1/4 cup / 25 g sliced green onions, plus more for garnish
• 1 to 2 fresh jalapeños, seeded and finely chopped
• 1/2 tsp / 3 g garlic salt
• 1/4 tsp / 0.5 g ground white pepper

Instructions

1. Prep Your Station: Preheat your oven to 350°F / 175°C. Generously grease a 2-quart casserole dish and set it aside.
2. Cook the Grits: In a large saucepan, bring the water to a rolling boil. While whisking constantly to prevent lumps, gradually pour in the grits. Reduce the heat and simmer, stirring occasionally, until thickened.
3. Temper the Eggs: To avoid scrambled eggs, slowly ladle about 1 cup of the hot grits mixture into your lightly beaten eggs, whisking the entire time. Once combined, pour this tempered egg mixture back into the saucepan with the rest of the grits.
4. Mix and Mingle: Stir in the shredded cheddar cheese, milk, 1/4 cup of sliced green onions, finely chopped jalapeños, garlic salt, and white pepper. Keep stirring until the cheese is melted and everything is beautifully combined.
5. Bake to Perfection: Pour the grits mixture into your prepared casserole dish. Bake, uncovered, for 45 to 50 minutes. The casserole is ready when the center is set and a knife inserted near the middle comes out clean. Let it rest for a few minutes before serving.
6. Garnish and Serve: If desired, sprinkle with extra sliced green onions for a fresh finish. Serve warm and enjoy!

Pro Tips

• Chile Caution: Fresh chiles contain volatile oils that can irritate your skin and eyes. Wear gloves when seeding and chopping them, and be sure to wash your hands thoroughly with soap and warm water afterward.
• Cheese Swap: Feel free to get creative! A blend of sharp cheddar and Monterey Jack adds extra creaminess, or use Pepper Jack for an even spicier kick.
• Don’t Scramble the Eggs: The secret to a smooth, custard-like texture is tempering. Adding the hot grits to the eggs slowly and whisking constantly gently raises their temperature, preventing them from curdling when added back to the hot pan.
• Make-Ahead Magic: Assemble the entire casserole (without baking) up to 24 hours in advance. Cover and refrigerate. When ready to bake, let it sit at room temperature for 30 minutes, then bake as directed, possibly adding 5-10 extra minutes to the time.
