A slow cooker turns inexpensive cuts into tender, flavourful meals with minimal effort — set it in the morning, return to a finished dinner. The most common complaint about slow cookers is that they run too hot, boiling rather than simmering and turning beans to mush. The best models cook low and slow as the name implies, and the Hamilton Beach Set & Forget has led category testing for over a decade.

1. Hamilton Beach Set & Forget 6-Quart — Best Overall
The Hamilton Beach Set & Forget has been the top-tested slow cooker since 2013 — it made the best pot roast in testing and critically, it successfully simmered beans on low without boiling them (a failure mode that eliminates most competing models). The built-in probe thermometer lets you cook meat to a precise target temperature (140–180°F in 5-degree increments): the digital display alternates between internal and target temp, then auto-switches to warm when done. The locking lid clips securely for transport. At ~$70, it does everything a slow cooker should do without excess.
- Built-in probe thermometer: cook to 140–180°F in 5-degree increments
- Simmons beans on low without boiling — rare for slow cookers
- Best pot roast result in head-to-head testing
- Locking lid clips for transport and serving
- Probe is short — may not reach small pieces of meat
- Plain design compared to premium alternatives
2. Hamilton Beach Temp Tracker 6-Quart — Best Temperature Monitoring
The Hamilton Beach Temp Tracker is the updated sibling of the Set & Forget, adding a cleaner interface and real-time temperature display throughout cooking — not just probe-triggered. The 6-quart capacity suits families of 4–6, cooking results are consistent with the Set & Forget, and the lid-lock handles double as a carrying mechanism. The best alternative if the Set & Forget is unavailable or if you prefer the updated interface.
- Real-time temperature display throughout cooking
- Updated cleaner interface vs. Set & Forget
- Lid-lock handles for transport
- Same reliable low-and-slow cooking performance
- Slightly more expensive than Set & Forget
- Less widely tested than the long-running Set & Forget
3. Ninja PossibleCooker PLUS — Best for Searing First
The Ninja PossibleCooker PLUS eliminates the extra pan entirely — its oven-safe pot handles direct searing on the stovetop (up to 500°F), then goes straight into the base for slow cooking. No flavour lost in transfer. The 8.5-quart capacity is the largest in this comparison, the integrated spoon rests in a built-in holder, and the glass lid lets you monitor without lifting. 12 cooking functions include sous vide and steam alongside slow cook and sear/sauté — genuinely versatile rather than a gimmick.
- Oven-safe pot to 500°F — sear on stove, slow cook in base, one vessel
- 8.5-quart — largest capacity in this comparison
- 12 functions: sous vide, steam, slow cook, sear/sauté
- Integrated spoon holder — no extra utensil rest needed
- Nonstick insert — less durable than ceramic over years of use
- Bulkier than a dedicated slow cooker
4. Crock-Pot 6-Quart Programmable — Classic Reliable Choice
The Crock-Pot is the category originator and the 6-quart programmable remains a dependable workhorse at under $50. Programmable cook time up to 20 hours, auto-shifts to warm when done, removable stoneware insert dishwasher-safe. Results are consistent and predictable — no surprises. If you want a straightforward slow cooker from the brand that invented the category and don't need probe thermometry, this is the honest budget-to-mid choice.
- Up to 20-hour programmable cook time with auto-warm
- Dishwasher-safe removable stoneware insert
- Under $50 — good value for a reliable workhorse
- Simple controls — set-and-forget without complexity
- No probe thermometer — can't cook to internal temperature
- No locking lid for transport
5. Russell Hobbs 22750 — Best Budget
At ~£25–30, the Russell Hobbs 22750 is the best entry-level slow cooker. 3.5L ceramic pot, three heat settings (Low/High/Keep Warm), a glass lid, and removable ceramic insert for easy cleaning. The right choice for single-person households or couples testing slow cooking for the first time. If you find yourself using it more than twice a week, the Hamilton Beach Set & Forget is the upgrade worth making.
- Excellent value at ~£25–30
- Removable ceramic pot — easy cleaning
- Simple three-setting control
- 3.5L — too small for families of 4+
- No timer, no probe thermometer
What to Look for in a Slow Cooker
Temperature accuracy
The most common slow cooker problem is running too hot — models that boil on the "low" setting produce tough meat and mushy beans. The Hamilton Beach Set & Forget specifically tested well here. If you're comparing models, look for reviews that test actual cooking temperatures, not just features.
Probe thermometer
A built-in probe lets you cook roasts and whole joints to a precise internal temperature, then auto-switch to warm — eliminating the guesswork that causes overcooked or undercooked results. The Set & Forget's probe (140–180°F range) is the most useful feature in its price class.
Capacity
3.5L suits 1–2 people. 6L handles families of 4–6 and most batch cooking. Food slow-cooks best when the pot is at least half full — an oversized pot for small batches produces poor results.
Hob-safe pot
Searing meat before slow cooking makes a significant flavour difference. The Morphy Richards Sear & Stew does this in one pot. Otherwise, you need a separate frying pan for the browning step — not a dealbreaker, but an extra step and extra washing up.
Our Verdict
The Hamilton Beach Set & Forget is the best slow cooker for most households — the probe thermometer, locking lid, and genuine low-and-slow temperature control make it worth the ~$70. For searing and then slow cooking in one pot without a separate pan, the Ninja PossibleCooker PLUS is the more practical tool. On a budget, the Russell Hobbs 22750 or the classic Crock-Pot 6-Quart are reliable starting points under £30/$50.
Frequently Asked Questions
Slow cooker or Instant Pot — which is better?
Instant Pot does both pressure cooking AND slow cooking in one device — typically the better single purchase. Standalone slow cookers (Hamilton Beach Set & Forget) are cheaper (£40-80 vs £120-200), simpler, and the timer/temp control is just as effective for slow recipes. For people who only want slow cooking, standalone is fine; for those wanting multi-function, Instant Pot.
What size slow cooker do I need?
1-2 people: 3-4 quart. 3-4 people: 5-6 quart (Hamilton Beach 6-Quart Programmable). 5+ people or batch cooking: 7-8 quart. Slow cookers work best half to two-thirds full — buying too large means dishes dry out, food can burn on bottom. The 6-quart size is the family standard.
Can I leave a slow cooker on while at work?
Yes, that's the design intent. Modern slow cookers like the Hamilton Beach Set & Forget have programmable timers and warm-after-cooking modes — safe to run unattended for 8-10 hours. UL safety certifications mean the device is designed to operate unattended. The 'set and forget' design is the entire point of slow cookers.
Why is my slow cooker meat dry?
Usually high heat for too long, or wrong meat cut. Slow cookers work best on low for tough, fatty cuts (chuck roast, brisket, pork shoulder) that need to break down. Lean meats (chicken breast) dry out — use chicken thighs instead. If using high heat: limit to 4-6 hours; on low: 8-10 hours is the sweet spot. Add liquid (broth, wine) to compensate for moisture loss.
