INGREDIENTS You’ll Need:

Here’s a chile relleno casserole ingredient list focused on quality over quantity because that’s what authentic flavor is all about! For the best flavor in your chile relleno casserole, I recommend sourcing fresh poblano peppers from your local farmer’s market or a trusted produce stand. You want peppers that smell vibrant and feel firm to the touch.

Fresh ingredients for chile relleno casserole including poblano peppers, cheese, tomato sauce, and spices.
  • 6 large fresh poblano peppers
  • 1 lb mild white cheese (queso oaxaca or Monterey jack work beautifully—see this Chile relleno casserole recipe with Oaxacan cheese for inspiration)
  • 1 cup tomato sauce, homemade or a quality canned variety with no additives
  • 1 small onion, finely chopped
  • 3 cloves garlic, minced
  • 4 large eggs, lightly beaten
  • 1/2 cup all-purpose flour
  • 1 cup milk (whole milk brings the best creaminess)
  • 1 tsp ground cumin
  • 1/2 tsp smoked paprika (adds depth and a subtle smoky hit that transforms this easy chile casserole)
  • Salt and freshly ground black pepper to taste
  • 2 tbsp olive oil or vegetable oil for sautéing

You’ll find freshest ingredients for this baked chile relleno at specialty Mexican markets or the organic section of your grocery store. For cheese, if you aren’t near Oaxacan cheese sources, Monterey jack or mozzarella work well though Oaxacan cheese’s melt and mild flavor make a noticeable difference in authentic flavor.

Here’s an chile relleno casserole flavor secret that transformed our family dinners: roasting your poblanos until the skins blister easily makes all the difference. It adds smokiness without adding heat, and peeling afterward creates a tender texture that stays soft through baking. If you have time, marinate roasted peppers in a light garlic and herb mix for 10 minutes before assembling. It deepens the flavor beautifully.

In my kitchen, I also pulse the tomato sauce with sautéed onions and garlic before adding spices to develop natural sweetness. That little prep extra pulls the whole cheesy chile casserole together so the baked chile relleno never feels flat or dull.

Let’s Create This Together!

1. Begin by roasting your poblano peppers over a gas flame or under a broiler until charred on all sides. This process usually takes around 10-12 minutes. Don’t rush it—the charring is essential for building that signature smoky tone in your chile relleno casserole.

2. Place roasted peppers in a bowl and cover with plastic wrap or a lid. Let them steam for 10 minutes to loosen skins. Once cool enough to handle, peel gently and remove seeds and membranes to reduce heat and improve tenderness.

3. While peeling peppers, heat olive oil in a skillet over medium heat. Sauté chopped onion and minced garlic until translucent and fragrant—about 3-4 minutes.

4. Add cumin and smoked paprika to the onion mixture. Stir until spices bloom and the aromas fill your kitchen. This is the moment where your chile relleno casserole really begins to sing.

5. Stir in tomato sauce and season with salt and pepper. Simmer gently for 5 minutes until thickened slightly. While this simmers, preheat your oven to 350°F (175°C).

6. In a medium bowl, whisk eggs and milk together. Gradually add flour while whisking to form a smooth batter. This batter helps bind the flavors and cheese in your chile relleno casserole during baking.

7. Cube your cheese into bite-sized pieces. Stuff each roasted poblano pepper with generous portions of cheese. Arrange stuffed peppers in a lightly greased casserole dish.

8. Pour tomato sauce mixture evenly over the peppers. Then gently pour the egg batter over the entire dish, letting it settle between peppers.

9. Place casserole in preheated oven. Bake for 35-40 minutes until the top is golden and the cheese inside is melted through.

10. When your chile relleno casserole hits the table, the kitchen should be filled with warm, inviting aromas of roasted peppers and melted cheese. Don’t be surprised if the family starts hovering nearby early.

Here’s where I used to miss a key step—roasting the peppers fully and letting them steam. If you skip this, the casserole texture changes drastically. Learn from my past kitchen adventures!
