Why This Recipe Works
Here’s the thing about pork tenderloin: it’s lean, it’s affordable, and it cooks beautifully in the slow cooker when you know what you’re doing. The balsamic vinegar and garlic create this amazing flavor base that makes the whole house smell incredible, and the hands-off cooking method means you can actually get other stuff done.
Plus, this recipe hits all the major dietary needs without tasting like “diet food.” Win-win.
Pro Tips
- Don’t skip the garlic coating – it makes a huge difference in flavor
- Use a meat thermometer – pork tenderloin is done at 145°F internal temperature
- Let it rest – give it 5 minutes before slicing for the juiciest results
- Save the juices – they make an amazing sauce for drizzling over cauliflower mashed potatoes.
What to Serve With This
This pork pairs beautifully with:
- Cauliflower mash (keto-friendly)
- Roasted Brussels sprouts
- Simple green salad
- Zucchini noodles
- Sweet potato (if you’re not doing keto)
Storage & Reheating
Refrigerator: Store leftovers in an airtight container for 2-3 days. Reheat portions for 30 seconds at a time in the microwave.
Freezer: Allow the pork tenderloin to fully cool to room temperature before transferring to an airtight freezer-safe container. Label, date, and freeze for up to 3 months. Thaw in the fridge for 12-24 hours prior to reheating.
