If you want an easy “put raw chicken tenderloins in a glass casserole dish + 4 simple ingredients” meal, try this creamy, flavorful baked chicken tenderloin recipe.
4-Ingredient Baked Chicken Tenderloins (Glass Casserole Dish)
Ingredients
- 2 pounds raw chicken tenderloins
- 1 cup salsa (mild, medium, or hot — your choice)
- 1 cup shredded cheese (cheddar, mozzarella, or a Mexican blend)
- 1 packet taco seasoning (or about 2 tablespoons homemade taco seasoning)
(Optional: add a little oil spray, salt, pepper, cilantro, or lime after cooking, but the recipe works with just the 4 ingredients.)
Equipment
- Glass casserole baking dish (about 9×13 inches)
- Aluminum foil (optional)
- Meat thermometer
Step-by-Step Instructions
1. Prepare the oven
- Preheat your oven to 375°F (190°C).
- Lightly grease the glass casserole dish with cooking spray or a thin layer of oil to prevent sticking.
2. Add the raw chicken
- Place the raw chicken tenderloins in a single layer in the casserole dish.
- Try not to overlap the pieces too much so they cook evenly.
3. Season the chicken
- Sprinkle the taco seasoning evenly over the chicken.
- Turn the tenderloins slightly so the seasoning coats both sides.
4. Add the salsa
- Pour the salsa over the chicken.
- Spread it around so every piece is covered. The salsa keeps the chicken moist while baking and creates a flavorful sauce.
5. Bake
- Cover the dish with foil if you want extra juicy chicken.
- Bake for 25–30 minutes.
- Remove the foil (if using) and sprinkle cheese on top.
- Bake another 5–10 minutes until the cheese melts.
6. Check for doneness
The chicken is ready when:
- The thickest piece reaches 165°F (74°C) internally.
- The juices run clear.
- The meat is white throughout, not pink.
Serving Ideas
Serve it with:
- Rice or Mexican rice
- Mashed potatoes
- Pasta
- Tortillas for chicken wraps
- Salad or roasted vegetables
Why this recipe works
