Learn Dutch: Het brood smaakt lekker. - The bread tastes good.

Dutch has two different words for tasting. Smaken means 'to have a taste' (as in, the food tastes good to you), while proeven is the active physical action of a person trying food (as in, 'I taste the bread'). Since the bread itself is giving off the flavor here, we use smaakt.

Why is lekker used here instead of goed for 'good'?

When talking about food or drinks being delicious, tasty, or enjoyable, Dutch almost always uses lekker. If you say the food is goed, it sounds more like it is of acceptable quality, healthy, or hasn't gone stale, rather than it being a joy to eat.

How would I add a routine time word like 's morgens (in the mornings) to this sentence?

You can put the time expression at the very beginning to say: 's Morgens smaakt het brood lekker. Notice that because the time word took the first spot, the verb (smaakt) and the subject (het brood) had to swap places to keep the verb in the second position.
