How do I reverse diet properly without regaining all the weight?

Great job on your progress! If your maintenance is really about 1,900 calories, I wouldn’t worry too much about having to reverse diet. Many people believe they’ll quickly gain fat by eating at maintenance, but that’s not usually the case.
If you increase your calories, it’s normal for the scale to go up by a pound or two because your body is storing more glycogen and water. This isn’t the same as gaining body fat.
I’d suggest adding 100 to 150 calories every week or two until you reach maintenance, or just go straight to maintenance if you’re happy with your weight and your workouts haven’t felt great. Try to track your weight over a few weeks instead of worrying about daily changes.

Try not to worry too much about reverse dieting. When you reach your goal, start increasing your calories back to maintenance slowly over a few weeks. Keep your training steady and keep an eye on your weight. If the scale goes up by a couple of pounds at first, that’s usually just glycogen and water, not body fat. Have you been tracking your weight trend during your cut?

Great work on the consistency. Most people panic at this stage and that is where the rebound starts. The advice from Cedric and Spencer is solid regarding glycogen, but there is a deeper hormonal layer you should consider to truly lock in those results long term.
When you have been in a deficit, your body has effectively down-regulated certain metabolic markers, specifically your T3 thyroid levels and Leptin sensitivity. It is not just about the calories, it is about "convincing" your endocrine system that the famine is over without triggering a massive storage response.
Instead of just adding 100 calories of anything, I would focus on the quality of those additions. Increasing your carbohydrate intake specifically around your training window will help signal to your body that it can safely up-regulate your metabolism again. This is called the thermic effect of food, and it works much better when timed with activity.
Also, keep an eye on your fasted morning glucose if you can. If you see it creeping up too much as you add calories, it means your insulin sensitivity is lagging behind your appetite. Taking it slow is the right move, but do it by "feeding the muscle" rather than just "filling the tank."
If you stay patient for those first 3 to 4 weeks of the reverse, your body will reach a new equilibrium where you can eventually eat even more than your previous maintenance while staying lean. That is the real metabolic magic.

Thanks for explaining things in detail. I hadn’t really considered the hormonal side before, just the calories, so now I have something new to look into.
I like the idea of adding most of the extra carbs around my workouts instead of just raising calories at random. I’m probably overthinking the scale, so it’s reassuring to know that a small increase from glycogen and water isn’t a big deal.
I am curious, have you tried this approach yourself after a cut? If you have, how quickly did you get back to maintenance without gaining much fat?

Lucy, I am glad that perspective helped. Dealing with the "scale anxiety" is the hardest part of the process, but remember: the scale is a liar, but the mirror and your performance are honest.
To answer your question: yes, I have used this specific metabolic titration approach multiple times, both for myself and when consulting others. The "gold standard" for a clean transition back to maintenance is usually a 4 to 6-week window.
In the first 2 weeks, I typically focus on restoring glycogen and up-regulating the thyroid response. This is where you see that initial 1-2kg jump on the scale, but your muscles will look fuller and your strength will return almost instantly. From week 3 to 6, I increase calories by roughly 150-200 every 7 days, but only if my morning fasted glucose remains stable.
The secret is to use your training sessions as a "sink" for those extra calories. If you are lifting heavy and the extra energy is going into the workout, your body is much less likely to store it as adipose tissue. By week 6, I usually find that I am back at my previous maintenance calories, but because the metabolic furnace is now burning hotter, I can often push even higher sometimes 300 to 500 calories above my original baseline while maintaining the same body fat percentage.
My best advice for the next month: stay the course, don't panic if the scale jumps, and focus on the quality of your sessions. You are not just eating more; you are rebuilding your metabolic engine.
Looking forward to seeing your progress updates!
