Yes. Under both the 2014 and 2024 Dungeons & Dragons rules, a Sorcerer who knows eldritch blast and has Quickened Spell can cast the cantrip with an action, then cast it again as a bonus action. Quickening one casting costs 2 Sorcery Points.
How it works under the 2014 rules
Quickened Spell changes the casting time of the chosen spell to a bonus action. The 2014 rule for bonus-action spells then limits other spells you cast on that same turn: they must be cantrips with a casting time of one action. The official Sage Advice Compendium confirms that this is how Quickened Spell works.
So you can cast eldritch blast as your action and quicken a second casting as your bonus action. The ordinary action casting is the one-action cantrip permitted alongside the bonus-action spell.
Cost and prerequisites
Quickened Spell costs 2 Sorcery Points per use under the 2014 Sorcerer rules. You need to know eldritch blast, have the Quickened Spell Metamagic option, and have an action, bonus action, and enough Sorcery Points available.

How it works under the 2024 rules
The 2024 Quickened Spell rule also costs 2 Sorcery Points. It prevents you from modifying a spell with Quickened Spell if you have already cast a level 1 or higher spell on that turn, and it prevents you from casting a level 1 or higher spell after modifying one. Those restrictions do not prevent casting another cantrip, so an action casting and a quickened bonus-action casting of eldritch blast are allowed. See the 2024 Sorcerer rules.
The separate 2024 spellcasting rule says, “On a turn, you can expend only one spell slot to cast a spell.” Cantrips do not expend spell slots, so that rule does not itself prohibit casting two cantrips on the same turn. The rule appears in the 2024 Basic Rules’ Spellcasting section.

What changes between the two rules versions?
| Rules version | Relevant restriction | Can you cast eldritch blast twice? |
|---|---|---|
| 2014 | After casting a spell as a bonus action, any other spell cast that turn must be a cantrip with a casting time of one action. | Yes. Cast one with your action and the quickened one with your bonus action. |
| 2024 | Quickened Spell restricts level 1+ spells before and after the modified spell; the general rule limits spell-slot expenditure to one per turn. | Yes. The restriction does not rule out another cantrip, and cantrips use no spell slot. |
Does the bonus-action rule mean you can only cast one spell per turn?
No. Under the 2014 rules, the relevant restriction is triggered specifically by casting a spell as a bonus action; it is not a general one-spell-per-turn limit. Under the 2024 rules, the general limit is on expending spell slots, while Quickened Spell separately limits level 1 or higher spells on that turn.
