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-compared slow cooker since 2013 — it made the best pot roast in published tests 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. Crock-Pot 6-Quart with Sous Vide — Best Temperature Monitoring
This is the pick if you want the machine to cook to a temperature rather than to a clock. A removable probe reads the internal temperature of the meat and stops guesswork on large cuts, and the same probe drives a genuine sous vide mode — a temperature-controlled water bath, which no ordinary slow cooker can do. The 6-quart stoneware suits families of 4–6 and goes in the oven and the dishwasher. At around $115 it is the most expensive cooker here, and that premium buys the probe and the water bath, not better slow cooking: for plain low-and-slow the Set & Forget above matches it for a third less.
- Removable probe cooks to internal temperature, not to a timer
- True sous vide mode — precision water bath
- Stoneware is oven-safe as well as dishwasher-safe
- 6-quart capacity for families of 4–6
- Around $115 — the most expensive option here
- Sous vide needs air-tight bags you buy separately
- Overkill if you only ever cook stews and chilli
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. Sunvivi 4-Quart Programmable — Best Budget
At around $45 this is the cheapest way in, and it is not a stripped-back one either: the timer runs from 30 minutes to 12 hours on low and 10 on high, with a digital countdown on the front, which is the thing budget cookers usually leave out. The 4-quart ceramic pot feeds two to four, and the locking lid clamps down so it travels to a potluck without sloshing. What you give up against the picks above is the probe — it cooks to a clock, not to a temperature — and 4 quarts is genuinely small if you are batch-cooking.
- Around $31 — a third of the price of the Set & Forget
- Timer to 12 hours on low, with a digital countdown
- Ceramic pot and glass lid both go in the dishwasher
- Locking lid for carrying the pot full
- 4-quart — tight for families of 5+
- No probe — cooks to a timer, not a temperature
- Half the capacity of the 6-quart picks above
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 Ninja PossibleCooker PLUS does this in the same pot — its base heats high enough to brown properly. Every other cooker here needs a separate frying pan for the browning step, which is not a dealbreaker but is an extra pan to wash.
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 Toastmaster 4-Quart Digital or the classic Crock-Pot 6-Quart are reliable starting points under $90.
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 ($30–90 vs $150–250), 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.
