What Makes Trader Joe’s Unexpected Cheddar So Special?

Trader Joe’s Unexpected Cheese
It starts off tasting like a sharp aged cheddar but finishes like a Parmesan — tangy, crumbly, and full of nutty depth.

Cook’s Notes
Why Casarecce Pasta?
Casarecce (pronounced kah-zah-RECH-ee) is a twisted, scroll-like pasta that’s practically made for mac & cheese.

Casarecce Pasta
Holds Sauce Beautifully: Its open folds and curved edges trap creamy sauces inside and out — every bite is loaded with cheesy goodness.
Ideal for Hearty Add-ins: It stands up well to crispy bacon, robust cheeses, and add-ins like mushrooms or roasted veggies without getting lost.
Great Mouthfeel: Casarecce gives you that perfect mix of chewy and creamy, unlike softer shapes that can turn mushy in the Instant Pot.
Visual Appeal: Its shape adds rustic charm and texture — perfect for a dish that’s as comforting as it is photo-worthy.
While you can use any short pasta, casarecce gives this dish a gourmet edge — and helps the Unexpected Cheddar shine through in every swirl.
Instructions
1. Cook the Bacon
Set Instant Pot to Sauté.
Add bacon slices and cook until crispy, 5–7 minutes.
Remove bacon and drain on paper towel.
Crumble and set aside. Leave 1 tablespoon bacon fat in the pot (for flavor!).
2. Pressure Cook the Pasta
Add pasta, water or broth, salt, pepper, garlic powder, and butter to the pot. Stir well.
Seal lid and set to Pressure Cook (High) for 4 minutes.
Once done, do a Quick Release and carefully open the lid.
3. Reserve and Stir
Scoop out 2/3 cup of the pasta water and set aside. Stir the cooked pasta (no need to drain).
4. Add the Cheese
Set pot to Keep Warm (or Low Sauté). Add milk, Gruyère, Unexpected Cheddar, and Parmesan. Stir until cheese melts into a creamy sauce.
Adjust texture by adding splashes of reserved pasta water until smooth and glossy.

5. Finish with Bacon
Stir in most of the crumbled bacon. Sprinkle the rest on top, with optional parsley, chili flakes, or smoked paprika.
