You can. It's called a CD. They currently return about 0.8%, which is the max you're ever going to get for a "risk free" investment right now. Anything beyond that is going to be some form of speculative investment. This is precisely why the stock market has become so inflated.
See TSLA for example.
Then just invest in a Vanguard ETF. There's no such thing as "risk free" money short of US treasuries or an FDIC insured CD, and those don't require any research.
