Deposit the 32oz of raw diced chicken breast into the unheated slow cooker. Top directly with the 28oz San Marzano tomatoes, ⅓ cup chopped sundried tomatoes, 1 Tbsp olive oil, and the entire dry spice blend (salt, oregano, garlic powder, chili flakes, black pepper, and parmesan rind). Stir vigorously until the raw protein is fully coated.
Secure the lid and initiate thermal extraction by cooking on High for 2-3 hours (or Low for 3-4 hours). The tomatoes will break down and the chicken will release its natural juices.
Remove the lid. Deploy two metal forks to shred the cooked chicken breast directly inside the hot tomato broth. The meat should yield with zero resistance.
Bring a large pot of heavily salted water to a rolling boil. Submerge the 24oz linguine and boil for exactly 50% of the time listed on the package instructions. The core must remain rigid and chalky to withstand the final slow cooker phase. Drain immediately.
In a high-speed blender pitcher, combine the 3 ⅓ cups 2% cottage cheese, 4oz ⅓-fat cream cheese, 1 cup Parmigiano Reggiano, and 1 ½ cups fat-free milk. Blend on maximum velocity for 60 seconds until the fluid is flawlessly smooth and the casein curds are entirely pulverized.
Transfer the parboiled linguine directly into the slow cooker, resting it on top of the shredded chicken. Cascade the blended high-protein alfredo sauce evenly over the pasta. Using tongs, vigorously fold the linguine into the sauce and chicken base until fully coated.
Cover and apply High heat for a final 15-20 minutes. The thermal energy forces the linguine to absorb the liquid, releasing starches that thicken the sauce into a cohesive, glossy coating.
Arrest the cooking process immediately to prevent the pasta from turning to mush. Divide the pasta evenly across 10 freezer-safe meal prep containers. Allow the steam to dissipate completely before sealing.
