Ingredients
- 1 pound rotini pasta
- 4 cups whole milk
- 3 cups shredded Pepper Jack cheese
Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a deep 9-by-13-inch baking dish.
Step 2: Add the Pasta
Pour the uncooked rotini into the prepared baking dish and spread it into an even layer.
Step 3: Add the Milk and Cheese
Pour the milk evenly over the dry pasta.
Sprinkle approximately 2 cups of shredded Pepper Jack cheese over the pasta and gently stir to distribute it.
Cover the dish tightly with aluminum foil to keep the moisture inside while the pasta cooks.
Step 4: Bake Until Tender
Bake for approximately 45–55 minutes.
Carefully remove the foil and stir the pasta. Check that the rotini is tender and that there is enough creamy liquid remaining.
If the pasta is still firm, add a little hot milk or water, cover again, and continue baking in 5–10-minute intervals.
Step 5: Add the Remaining Cheese
Sprinkle the remaining 1 cup of Pepper Jack cheese over the top.
Return the uncovered dish to the oven for another 8–10 minutes, until the cheese melts and becomes bubbly.
Step 6: Rest and Serve
Remove the casserole from the oven and let it rest for about 5–10 minutes.
Stir gently if desired, then serve warm while the cheese is creamy and melted.
Tips for the Best Pepper Jack Rotini
- Use a deep baking dish: The pasta needs enough room to expand as it absorbs the milk.
- Cover tightly: Keeping the dish covered helps prevent the milk from evaporating too quickly.
- Stir halfway through: This helps distribute the liquid and encourages even cooking.
- Shred your own cheese: Freshly shredded Pepper Jack generally melts more smoothly.
- Check the pasta: Oven temperatures and baking dishes vary, so check for tenderness before serving.
- Let it rest: A few minutes of resting allows the sauce to thicken.
Easy Recipe Variations
These additions are optional and will increase the ingredient count.
- Extra creamy: Stir in a few tablespoons of cream cheese.
- More heat: Add sliced jalapeños or crushed red pepper flakes.
- Garlic flavor: Add minced garlic or garlic powder.
- Protein-packed: Mix in cooked shredded chicken or browned ground beef.
- Colorful vegetables: Add steamed broccoli or diced bell peppers.

Storage Instructions
Refrigerator: Store leftovers in an airtight container for up to 3–4 days.
Freezer: Freeze cooled portions in freezer-safe containers for up to 2 months. The texture may become slightly softer after thawing.
Reheating: Warm in the microwave or in a covered baking dish at 325°F (165°C). Add a splash of milk before reheating to bring back the creamy consistency.
Frequently Asked Questions
Do I need to boil the rotini before baking?
No. This recipe is designed for uncooked rotini. The pasta absorbs the milk as it bakes, so make sure the dish is tightly covered and check the liquid level during cooking.
Can I use a different type of pasta?
Yes. Penne, fusilli, or medium shells can work. Cooking time may vary depending on the pasta shape and thickness.
Is Pepper Jack cheese spicy?
Pepper Jack has a mild to moderate kick from the peppers mixed into the cheese. If you prefer less heat, you can replace some of it with Monterey Jack, although that changes the three-ingredient recipe.
Why is my baked pasta still hard?
The pasta may need more liquid or additional baking time. Add a little hot milk or water, cover tightly, and continue baking until tender.
Can I prepare this casserole ahead of time?
For the best texture, bake it shortly before serving. Uncooked pasta can absorb the milk unevenly if left sitting for too long before baking.
